Great Video, really useful to know how to treat fish. I have read books, but nothing explains it as well as your demonstration, thank you.
Thanks for the advice. One of my clown loaches has a white mouth and I have a jug of this stuff in the back of my fridge. I hate catching loaches, they're so fast.
That was so informative, I really didn't know how to use Methylene Blue, Thank you for a really great video.
Hola
Ty for the info very straightforward and to the point as well as very useful informative thank you sir.
Thanks man! Answered all my questions! 😊
There are times when one should use this dye in an isolation tank, as you indicated. But there are times when you need to use it on the whole tank, as in the case of an ich infection. Removing only infected fishes for treatment would leave the parasites in the tank and make the inhabitants subject to reinfection.
For an ich infection, raise the temp to 80 degrees. remove all disposable filter material such as carbon and polyester fiber. Add an airstone and add the methylene blue. When all the ich spots have been absent from the fish for a couple of days, do a 50-30% water change. Put activated carbon in the filter chain to remove the remaining dye. After the blue is gone, put in fresh carbon and continue water changes once or twice a week for a month in order to prevent ammonia buildup while your bacteria bed is reestablishing itself in the tank.
Never use methylene blue (or malachite green) with scaleless fish (loaches, some catfish) or invertebrates.
Treat (sterilize) any new fish or plants to avoid introducing infection to the tank.

I wonder about m/blue use for fish with damaged gills resulting from the cyanide used to collect them. My understanding is that the gills are permanently damaged and the fishes likely will waste away. If the m/blue gives some palliative relief, good, but try to check out the collecting methods of the fish supplier and avoid buying those fish. Difficult I know. Did you ever get dosing info for this procedure?
+PalJoey1957 Thanks for chiming in, I used some of this info as part of my research to help one of my little fish and he survived. I appreciate as I'm sure my fish does.
how do you sterilize a plant???
How to sterilize a new fish? And how long will it take?
Thanks for this video! How often should I do a bath like this?
If I keep a tank ready with the tank dosed how long does it last before I need to redo the mixture?
Oh I just realize I frequently saw some fish in the market packed inside a big plastic bag and it was filled with blue water now I know why the water is blue then since the caught fishes from somewhere far will take a day trip to be delivered in the fish market to prevent ammonia and nitrite buildup inside the bag they use methylene blue to neutralized or minimize it.
I went to pets at home to get advice for my catfish with a white spot. they did a water test and gave me white spot and parasite treatment. I was advised to add after water change in my tank with 18 fish. I've added it and now worried after watching this.
What is the concentration of the Methylene blue.. And do you use Methylene blue one time just before hatching of the eggs or how many times?
Thanks for this video...
i had a neon with a fungal infection in its dorsal fin i did not know what to do and within about 6hours it was nearly dead and other fish where atacking i did not know what to do and put 2 pipets or methelin blue in the tank as i did not know how it effected filter media or plants then i found out because someone told me and i saw your video it havnt effected my tank yet and i hope it will not and thanks for the informational video
Excellent tutorial thank you so much
I leave my betta for about 1hour and just 2 drops. I've done it for a week now still the hair like fungus still doesn't recede I'm hesitating to use any fish antibiotics since it's a miss or hit kind of thing.
I have got two tetras with a white growth on their mouths i have tried two different antibiotics so far and no change so i am going to treat them with this im at a loss if it doesn't clear it .
Black Louis, I'm a betta expert and I always use methylene blue for betta fish. You must respect the dosage for your betta fish.
+thang antoine how much to add ?
+thang antoine how long should betta stay with methylene blue?
+Romulus Marcus it depends, but my bettas can stay about 1 day in MB(powder form) mixed with water
Should I give food to my fishes while fungus treatment on ?
Could you use this on marine fish as well?
Will it dye my white Molly's blue ?
Wish i watched this like half hour ago, just done my main tank because white spots cropped up :/ got amphibians and loachs so can't use the drug treatment.leanred for next time though thanks. Luckily silicones black and stones are blue already
Will it ever like. Help the mold or stuff on the side of the tank.
Happy for the tutorial on the Methylene Blue. Cheers bruv. How would you dose a 20 gallon tank with freshly spawned Discus eggs? Thanks for replying.
5 ml of methylene blue on 20 gallon tank but on your emergency tank not on your main tank be sure your air pump on emergency tank is in low
also add a pvc pipe or artificial plants for your fish to hide
add a bit of aquarium salt if the fish has scale. dont add aquarium salt when the fish is scale less it will harm them
use aquarium salt for freshwater dont use reef salt use reef salt if your fish is saltwater fish. DONT USE A TABLE SALT
Can you feed fry infusoria when the tank has methylene blue?
Do you mean to leave the effected fish in the quarantine tank for 30 minutes a day for 2 weeks with methylene blue diluted in water?
What percent dilution is your methylene blue in that small dropper bottle?
I was thinking of using metholene blue in a QT also treating with cupramine for white spot saltwater Will the metholene blue kill the bacteria?
How about treating betta and guppy fry with this also do I use conditioned tank water and mix meth blue or just fresh water from tap need to know asap as my betta in breeding box trying save my dudes life
About not using with scaleless fish such as loaches, Over the years I've had some major outbreaks of Columnaris and Ick. I have found that half dosing with loaches has been effective and safe. My only Loach casualty has been been Copper who was hit with Strain 1 and died within 48 hours. And did not have the Methylene Blue. I'm not an expert I just wanted to give my experience in hopes that it could help someone else.
@@xKenn. Good luck on a answer. That was years ago but the guy in the video said 30 minutes.
Bravo! Thx a Million!
Excellent tutorial thank you so much :)
does it have scale and is it saltwater??
sorry im just 10 years
@@PrinceHarrison_ well you are 15 now
I have 5 goldfish and two mystery snails and a sucker fish in the diluted methylene blue in a container with a air pump. They have definitely some kind of disease. How long do I leave them in that tank for before I transfer them back to the regular tank after disinfecting it all?
did the neon survive! i did the and the fish died soon after did i over dose it?
If the ich doesn't disapper after keeping the fish in methylene blue for 30 minutes in the 1st day, then what to do next?
im using the methylene blue in my tank. It has fake plants and gravel substrate. I took my filter cartridge out, have a filter and airstone running thought the tank.
How much time should the fish be immersed with water having Methylene Blue?
Hi
Is that clean tap water or water from your tank??
This is probably a long shot because this video is old, but long story short is I had to tear down 2 tanks tonight and all my fish are in 2 plastic storage drawers with air stones. I put a drop of Blue in each tub……. I’ve been desperately trying to get stuff set up but I’m so exhausted…. If I leave them in over night will they die?
Thanks for the video. I am having a real problem treating the fungus on my recently purchased adult Leopoldi Angelfish - I bought some commercial Methylene blue but the leaflet advises dumping it in my main tank!
how long can mythelene blue kill al the beneficial bacteria on my filter? I accidentally put it on my tank with filter
New fish before placing in quarantine tank, before adding quarantined fish to main tank, and aiding healing in sick fish.
When I get new fish should I do a bath with this how long a teaspoon per 10 gallons?
But unless yu treat your main tank, won't the ich in the substrate infect the fish again? Confused
I watched a science video, that showed this substance, turns blue when you shake it in a jar, and as the oxygen bubbles out of the water (within maybe 20-30 seconds) it turns clear again. He said Methylene Blue is a "universal indicator" and is a "reversible chemical reaction".
Jay H Well, Methylene blue is not a proper pH indicator. You are most likely confused with methyl violet or something like that. It is great however as a dye or to treat methemoglobemia in humans.
My mirror koi fish has a red spot on her gills will blue drops work?
How much water to how much methylene blue? How do you do that for a bigger fish like a cory catfish?

Hi, I purchased a betta fish who developed this cotton-like growth on its body. I kept him in a 6 gallon fluval edge tank with a filter and heater set to about 79F. Unfortunately this is the second betta that developed this fungus growth and died within 3-5 days of purchase. I followed instructions regarding regular 25-30% water changes every other day and always used a water conditioner to top up the water. I am not sure what I am doing wrong. Would you suggest I quarantine any new betta in methylene blue before introducing into the tank? Also do I replace 100% of the water if my fish died in the tank and clean out the ornaments (I dont have real plants only silk smooth plants and smooth rocks)? Lastly, I noticed that the fungus developed usually after feeding my betta freeze dried blood worms. Could the diet affect them? Sorry for the long questions... I am new to this hobby.
Hi I hope that you still interest in this hobby otherwise I will be losing my time doing this, I have a betta who had the same problem. This is what you have to do 100% water change every day, keep him in 1 gallon of water can be tap water without conditioner betta are very strong fish and the tap water may actually help more. Be sure of cleaning the jar(made of glass not plastic) with a sponge that is clean of chemical. Use melafix and quick cure. Keep doing this until you see the that the fungus have disappear. My betta is alive and have being living with my for over 2 years.
Hi David, thanks for your response. I am still interested in this hobby. I have since held back on buying any fish till I do my full research on them. Its devastating when you have a helpless fish that you can't help and dies. I am looking into other fish that can withstand my fluval tank. Also I may not have done a good cycle with the water. I was advised to buy the api fresh water test kit to have proper water conditions (I.e. check ammonia, nitrites, nitrates, etc) for my fish. Its intereting that you state that they can withstand normal tap water. At this point I have spent like $400 plus and don't really want to keep having to spend more. Again thank you for your response! Have an awesome day!
david rodriguez
Your crazy using tap water the chlorine can kill them..that's 101 of Betta caring ..
+david rodriguez "tap water might help"?!? you're nuts.
if the water is new add water conditioner and expose it in air for 24 hours and float the fish bag on your tank for 15 mins. and add a scoop of your aquarium in your fish bag and free them after 50 seconds
I think my fish is addicted to methylene blue.
He had a terrible fungal infection and we alternated salt dips with methylene blue in the tank (1tsp/10Gal).
After 3 weeks, he recovered, got very active and we returned him to his outdoor pond.
Less than 24 hours later, he beached himself, and almost dead, we brought him back into the hospital tank in plain water. Next day he looked horrible, so we added methylene blue. Today, he is happy again and swimming normally. We joke he is a meth head now.
In all seriousness, has anyone else experienced this? He is a pond goldfish.
I guess this is why I'm putting it in my pond.
The fish will die or livr
I have dajana fmc drops 100 ml is that the same of methylene blue
I added 4 cap of this liquid in my 60 gallon tank looks like it have effected good bacteria as tank has started stinking. Will effect of this chemical degrade over time in 1-2 days or I will have to replace complete tank water
But we don't know the concentration of the methylene blue....or the ratio to the water.
Is this product safe to use on clown loaches?
Can I use this for my turtle?
Thank you
How long should i soak my fish in the solution?
Can I try this with African Clawed Frogs?
Granted, I won't. I've had to put them in a 25L fresh set up, the fungus is persistent so I'll try 2-3 days with 24hr water changes.
Is that fish saver ??
Help I put it in my good tank I need help will it kill my fish I don't want my puffers to die wat will happen wen all the good bacteria
Hi, I'm worried sick about my Black Moor who appears to have fungus infection and I can't find any answers nowhere. I hope someone can advice me.
My infected fish is already in a hospital tank. Now I've added the recommended dosage of methylene blue per liter and also placed an air stone for oxygen. Now my questions are:
(A) Won't my fish need beneficial bacteria anymore?
(B) Can I / Should I feed my fish?
(C) How often or do I even need to do water change?
(D) When should I add more methylene blue?
Pleaseeeee
Bro where we want to buy that medicines
My betta has a bump on his head and I think it's fungi because I haven't cleaned his tank in a month and a half. I had no time, usually I clean every 2-3 weeks. Please help me
Do a 25% water change each week. Unless you already killed your betta
How long can we keep the blue water with the fish like if we keep the fish in the blue water for a week will the fish die?
You can keep it in there it’s not dangerous just make sure you do your correct measurements and research.. if you do it properly then your fish will not die.
How long and how often should i use methylene blue?
5days
I thought were only supposed to dip the fish for 10 seconds? It says that on my bottle, and the guy at my LFS told me to only do 10 seconds. I have a betta with fin rot that I'm treating. I simply dip him and then put him in clean tank water to wash off the MB and then place him back into his regular tank that's treated with betta fix. Am I doing this right? I'm new to treating fish for illnesses but not fish keeping. Most of my fish are healthy, but bettas are very sensitive.
+Alicia Velasquez I have the same prob,my betta has something wrong with fins,maybe fin rot...not sure.i am going to get MB today if I can find it. I have been treating him in betta fix and aquarium salt.hows your betta now?did it work?
I don't know if you still need answer to this, but I actually keep my fish in a tank with methylene blue for 24 hours and then change the water and treat again.
So my sick fish are in the water with methylene blue constantly and I've had great results.
Katrine A hi... ...how many hours should i wait to change water....and should i change all water or just 1/3...?
Katrine A ma fish has fin rot n a rusty colour. In there fins too n i have lost many fishes due to this in a past few days what should i do i have seperated the more affected one wid the less ones n dipped them in this medicine
Keep doing what you're doing. Methylene blue doesn't work in just 1 day, it's gonna take some time.
please dont put it in your main tank, it will kill all your good bacteria and it will kill plants, make a quarantine tank even if its a large tupperware container or storage container. You will end up reversing all your tank cycling if you put it in your main tank.
Thank you! I wanted to know this. Looks like I have to use air stones to aerate the hospital tanks for my Bettas.
this is so fucked up. i just put it on my tank before i viewed this video
@@kurtstvn1942 lol
where can someone buy this stuff easily?
Methylene blue is good or bad for scaleless like catfish???
Do your research on it, and it should be ok
Great just watched this after adding to my tank 😤 doesn't say not to add to the main tank on the bottle
So is that why fish are sold in blhe water? They look full grown....
EVERY DAY 30 mins for two weeks?
Kindly clarify wether methylene blue can really kill aquatic plants, up to what dosage do you consider it to be dangerous for plants?
yes it will kill plants and snails, shrimp. etc...
Old comment, but just to clarify...
You don't put methylene blue in your tank. It's used for dips/baths in a separate environment, then the sick fish is returned to the tank.
I use it all the time in hospital and spawning tanks.
liz cooper Those are "separate environments" by definition, ie not the regular tank. You don't put methylene blue in your regular tank.
Thanks for the info. I appreciate it a lot :)
So I heard methylene blue can prevent diseases but your saying it can actually treat stuff like ich and dropsy?
Dropsy is like the last stage of cancer they said.
Nice idol
I use it on main equarium
Given bad advice by fish store added to my main tank ditched it as soon as I found out and cleaned the thing top to chucked an old filter on for now with pre cycled media and bb in a bottle and all that jazz how long is it going to effect my main tank even though it’s cleaned and my fish ?also is running carbon through my filter worth it to try draw out any meth blue that’s left after I tear it to pieces boil my ceramics and scrub my shit clean like seriously I love my fish more then my self at the moment like is all my shot gonna be blue for ever are my plants gonna die how can I clear it out my fishes system so it’s not transferred to the main tank once cycled again fuck my life hard
Can I do more than one fish at a time?
Yes you can do as many as you like
Has anyone ever used Methylene Blue, to treat - Swim Bladder Disorder, for their freshwater aquarium fish?
Thank you kindly!
Methylene blue has no effect on sbd. Try fasting the fish for 4-5 days, feeding boiled skinned pea, and epsom salt baths.
i use in my tank but very little amount ...
is it safe to use on corydoras?
Aaron McGinty oh yes
It saved mines
Where can I buy the methylene blue?
SUSAN Van Noy pharmacists
Isn't this the blue liquid in shipped delivered fish bought online? 🤔🤨
I want to know this. We got two Oscars delivered in blue water. Why?
yep
@@tegangayford1467 to sterilize the fish, keep it free from infections and prevent ammonia build up during transit.
4 drops TO HOW MUCH WATER?
Never put it in your main tank. My 5ft tank is stained forever. Now the tank is tinted blue.
quarantine/hospital tank.
it died im afraid, i think it was too far gone, you cant really overdose its just sometimes the fish is too far gone to be saved
South east asia knowledge here, i think youput it too much, usually instruction said 1drop for 2L of water
OMG 😱 I put my fish with methylene for almost 24hrs now coz all my fish got white spot 😭
The fish may of actually had neon tetra disease
I shouldve watched this before putting meth blue in my tank
Why
I added 4 cap of this liquid in my 60 gallon tank looks like it have effected good bacteria as tank has started stinking. Will effect of this chemical degrade over time in 1-2 days or I will have to replace complete tank water.
@@vijayshankarguptavijaygupta it is recommened to not to add it to tank as it will kill good bacteria too so treat ur fish in hospital tank
@@Syndra_maximoff1 sure but what to do about main tank where I have already added it, should I replace the water completely or effect of methalyne blue will come down automatically
@@vijayshankarguptavijaygupta since you added to the main tank.. just treat it in your main tank.. no point in hospital tank when ur good bacteria in your already died, also effect of methelyene blue doesnt go down.
Hi. Anyone who can answer this please as my methylene blue water is currently stored. I also realized not much fish keepers are actually aware of proper disposal methods
How do you dispose of this blue water?
Normally, water from my tank is dtored and i use it to water plants.
Is methylene blue same as antibiotics that you dont pour them straight down the drain?
Do i throw it down the drain? Do i water it in soil? Methylene blue is known to kill awuatic plants. I really dont know. Anyine who will answer is such a great help. Thank you so mucb
this is a methylene blue bath..for fresh water..12mg/L methylene blue solution for 10 minutes
How do you measure 12 mg from a dropper? How does one get 12 mg in volume, unless you weigh it? It would depend on the w/volume of methylene blue you have, they're not all the same.
@@Inapeartree I get a solution with known concentration from the pharmacy and then dilute the proper amount of it to the proper amount (I do the math) of dechlorinated water. I don't use the dropper to measure it, I use a siringe with ml markings on the side. And, yes, the amount of the solution you would use depents on the initial concentration. And yes, the concentration is in w/v because meth blue is initially a powder, 1% solution means 1g of meth blue in 100 ml solution.
@@mariakoth ah yes. Makes sense. I was wondering how to do this with my basic bottle of methylene blue.
My bottle of methylene blue only says 4 oz, 118 ml. I looked around the bottle and the only other information is 5 tsp per 3 gallons will give 50 ppm.
I actually ended up doing a calculation to get the volume down to 0.5 L solution. Tsp to drops, gallons to mL.
Ps it will kill your plants
Dang it I just added 30ml of this stuff straight into my tank...
Did your fish turned blue or something lol
@@dcuyu Yes...
I thought it should be just one drop per 10 gallon?
right....what is showing in this video ...
Right after I put methylene drops fish died
I gave itno main tank it will destroy my internal filter .
is this safe for saltwater fish?
yes but add reef salt
My 10 fish did that they all died.. 😭
You prolly put to much
I understand everyone's desire to have fish and an aquarium but sea life belongs in the sea.
These aren't from the sea. By the way you want to talk about reducing life form suffering then you should consider preaching anti natalism to the human populace instead.
Every time he says “um” take a shot
If this guy robbed a bank, they'd be closed before he finished talking.
Stupid pet shop lady told me to add it to main tank and I did.
