- Some of the best algae-eating pond fish, You probably came across our video by searching for algae-eating pond fish. well in today's video I will talk about a few fish that will eat algae in your garden pond.
Hardy - algae-eaters you don’t need to take inside for the winter
Pond Loach (Misgurnus anguillicaudatus) - dojo or weather loach
40 to 77°F, and are well-suited for beginner
foot in length happy with docile fish
Koi and Goldfish - omnivores and will indeed feed on algae to some extent, more so in the winter months, do rely on them goldfish and koi really do prefer other types of food
Grass Carp (Ctenopharyngodon idella) - Originating from Asia- different teeth, eaters of potentially problematic aquatic vegetation, won’t typically consume filamentous algae
Are Pond Fish Enough to Control All Algae?
As a rule NO - grow faster than fish can actively consume it, graze down algae during the cooler months
The only realistic way to control it would be through more traditional methods:
UV clarifiers, pond vacuums, barley straw, and even natural algae deterrents, such as pond plants.
* UV Clarifiers (Green Algae)
* Pond Vacuums (String Algae)
* Barley Straw (All Algae - Long term)
* Pond Plants (All Algae - Long term)
* Water Quality Tests (Slowing Algae Growth)
* Good Quality Fish Food (Less Waste)
Tropical - algae-eaters 10oC or 55-75°F
Pleco’s plecostomus - over 12” long, from South America,
Chinese High-Fin Banded Shark (Myxocyprinus asiaticus) - slow growers but 4 feet, only really suitable for very large (and deep) pond designs,
Siamese Algae Eater - 4 - 6”, most popular as they are energetic (with the character) and adept algae consumers, all types of algae, however, can stress out any calmer fish social species and need much Warm pond water approximately 70 and 79°F

With your hand moving like that, the fish thought you were going to feed them. Very funny! Good video
Thanks
Thanks for watching, yes they are always hungry
Fascinating! I had no idea koi eat algae, in the winter I thought they just kind of shut down and in the summer it’s what I feed them that keeps them alive. Brilliant video although I’ve never heard of the shark you mentioned or the other fish. I’ve noticed a new style to your videos too, I like it. Thanks Mark keep them coming
Thank you
Great video Mj! was always curious! 👍🏼
Thank you
Great information as always! Fantastic seeing you at Pondemonium!
thank you, yes this year was magical and I can't wait to watch more from you guys
Great restaurant analogy.
Short Sleeve thank you, it so true isn’t it.
I had little knowledge fish ate the algae. Good to know so when I’m away on holiday I don’t have to worry too much that the fish are starving. As always a video full of information thanks
Charlotte Wilson thank you, it’s amazing on how much they will eat (if it’s available). Duckweed is a great holiday food for a fish pond, it’s also being looked at by some Dutch scientist for a new super food. So the koi might have to start competing with humans. Algae is a big topic.
Brilliant video. I've got three huge weather loaches and an albino grass carp in with my kois, shubs, oranda and black moor. Short algae on the sides and bottom of the pond is all I get. No issues anymore but still found your video interesting!
Thanks for sharing your experience
useful advice. just starting a small raised pond. Cheers
My pleasure
thank you for the info!
Thank you for watching
Thanks for the info good video
My pleasure
Omg....I can't wait for my kids to get that big! I only had them for a year
Nice kois!!!!
thank you
Thanks
kimuseni thank you
Thank you SO MUCH for doing a video on this, it has helped so much! And saved me so much searching around! I saw you on Greg witsticks channel recently too, will you be using aqauscape products in your pond builds soon?
We have been building with aquascape products for seven years. What would you like to see a video on?
Greg Wittstock is a friend of mine, would you like to ask or suggest a topic for us to cover?
Keeping duck ponds clean vs keeping fish ponds clean!!
Platies will eat string algae and breed like crazy. But you can't keep them outside all year in the UK :(
Good video.. carry on 💟💗
Thank you
Stay Beside me brother💞💗
Elements of truth... Nice ending covers the fact they won't make much difference and to be fair alge is less of an issue in the winter months due to several reasons none of which really are to do with koi eating... Nore grass carp in that respect either... Can't fault your vids on the whole though ✌️
Thank you
Nice video mate 👍👌
thank you
Can weather loaches stay outside all year round in the u.k?? Good videos btw.👍
Yes
They are very hardy practically bullet proof n get to a good size in a pond
I’ve got a 125 gallon pond with 3 goldfish so I’m considering getting a Pond Loach to help keep the algae down.
Nice
Can dojo loach handle colder temperatures? My winters only have very light frost(if none at all sometimes).
The ones we get here in Europe are ok.
I have a small pond 750 lt in UK, with 9 goldfish. Last winter some of my plants/lilies frozen and they are picking up again but in the meantime algae grew everywhere. Remarkably the water is in pristine condition, super clean. I am thinking of adding a few good algae eaters in there as well but not sure which will do the job enough, and I don't want to drug them out in the winter. Any thoughts? And do I need to worry since water ins pristine? I mean, fish look happy and isn't algae building a natural habitat? Thank for any input.
Yes algae is a good thing, unless it’s getting out of hand. If you need to control it use Multi Clear it’s an active product not chemical based
@@ThePondAdvisor Thank you!
Will they survive in huge natural beaver pond without fountain to bring oxygen in? I'm looking for some fishes to clean lilies and other plantation. They grow all over covering the pond in the summer month
Survive yes
Thanks for the info. I'm thinking of putting my pleco in the pond during the summer would you say mid spring time is too early to put him In?
Get a thermometer, wait for the water to be stable
@@ThePondAdvisor ok will do. Thanks again
My Pleasure
I desperately need to update and relocate my pond - is this something that your company can do.? I live in South london
We can have a conversation
These are the fish tend to happen? makes sense to me!
Pond fish 🐠 🐟
hi i have a 8000 fish pond "tilapia and the bottom of my pond is full of food and fish waste would an algae eating fish help and if so which type
Great question, no algae eating fish will not eat fish waste. Do you have a filter?
For those watching in North America...
Grass Carp (From China) is an extremely invasive species and banned from use in ponds, rivers etc...
You will get heavy fines if you're caught willingly introducing grass carp into any eco system in North America. In fact you're expected to contact ministry of environment even if you suspect presence of grass carp or you catch one.
Most of the world is the same, no one should introduce anything into any natural water way!!! We need a license for a lot of fish in earthen ponds. Garden ponds as pets they are fine (the ornamental trade but big no no for lakes and rivers).
Yeah. Even grass carp don’t like the filamentous algae. Channel cat maybe, but here in Upstate NY we can have grass carp but have to get a permit for em
@@ThePondAdvisor
Problem is that a lot of so called pet specimens in people's small ponds end up in rivers, lakes and streams because once some people decide they don't want the fish any more they dump them to those water ways.
@@googlreviews7813 yes, i have seen this with my own eyes. Very sad
Good day sir. Im planning to build a small pond around 500 gallons with maybe 65watts pump. What fish can you recommend? And max number of fish that i can put in order not to get the pond dirty so fast
Great question, I have a video on the subject th-cam.com/video/ehU9dmh0lL4/w-d-xo.html
Hi. Considering getting a few Grass Carp for my pond to help control algae/pond weed but I also have some water lilles. Will they eat them too? Basically I don’t want them too.
Yes they will eat veggies, depends on the pond, the size and variety of lily. Are they common or big? Is the pond natural earth in or do you have a liner?
The Pond Advisor I have just made the pond a bit bigger so currently crystal clear water but I know algae/pond weed will come come as it’s in the sun all day. The pond is about 2,200 litres so not that big. It’s liner and I’ve put 2 pots of pond lillies in, small leaves
My pond has no flow, but it’s very large, I need some fish who will be able to survive in stagnant water and also under the ice in winter, which fish is best? Thx
Goldfish are the hardest fish on the planet
I have the all in one pond pump 6 in 1 for 9000gals I only have 4000gals in my pond.
1 koi
3 ghost koi 1 babey
4 gold fish
Any surjections on what aglie eaters you can recommend for my pond to help it clear it that bit extra thanks
I would look into a bigger filter. We don’t rate these filters as they always state more on the box than we recommend. A lot of work a lot of attention. Look into aquascape ecosystem ponds. A lot less work and less algae!
@@ThePondAdvisor can you be abit more specific with what you meant and just brought this one I was also thinking of building a waterfall feature with a extra UV light to help?? Would this maybe be a good idea?
Hello Mark. I was wondering, why do people always look into algae eating fish to combat string algae etc, and not other solutions, like daphnia, scads and snails? Daphnia helps me with the green water, scads with the string algae, dead fish, fish poop, dead plant matter and snails with brown algae etc.
Snails tent to overpopulate, so one or two crayfish can keep em under control. In my case I utilized the availability of our local river crabs, Potamios to control snail population while adding a far more interesting ''wild life diversity'' in my pond than just fish. I bet you probably do have local freshwater crayfish or crabs in the UK. You also have some freshwater shrimps in the UK, and if added in the pond BEFORE the fish and given some time, they can build a population that will stand after adding the fish. Shrimps will also eat all the algae and dead matter, plus dead fish and mosquito larvae etc.
Yes it’s crazy, wildlife are fantastic, algae is the start of life
Hey, i'm not english, i live in spain and i have a pond with string algae problems, could you explain me what scads are, i can't find what are those, ty.
@@ponchosmou6450 google search ''iberian freshwater amphipods'' to find out more about your local ''scad'' species. Most of continental Europe has Gammarus pulex, you can use them but you may find something else locally that suits better your conditions. You can collect them with a fine mesh net either in ponds or streams. I wade into the stream, place the net in the water touching the bottom, and then move / flip the rocks and disturb the sand above / up-stream of the net, the scads get swept by the current from under the rocks and end up in the net. Google your species before doing so and learn how to id your local species because you don't want to move around any potential invasive species, and you don't want predatory amphipods, you want the algae eating species.
I rarely feed my koi and yet they are fat. I can’t get rid of the algae so I’m sure the fish don’t mind. I try to feed them food I buy at the store and they barely go for it.
They will be eating something else in the algae or the quality of the water need attention
Hi, please can you help? I filled a new pond with rain water and planted lilies in baskets of pond soil off Amazon. The water has turned brown. The filter isn’t removing the brown colour. Will this hurt the goldfish I want to put in? How can I clear the water? Thanks
Depending on the colour brown. If it's like black tea then watch this video th-cam.com/video/uB_n2CrSJzM/w-d-xo.html and this is the link to buy the carbon waterfeature.shop/products/aquascape-activated-pond-carbon
If it's brown water like coffee with milk waterfeature.shop/products/clear-for-ponds-16oz-473ml
Thanks so much. It’s murky brown water since I put the compost in. It was clear before I added the lilies. I’ll try the carbon. Thanks so much x
I cleaned out the filter today. After 24 hours it pulled out so much of the brown compost!! I’ve replaced the sponges with new carbon sponges and ordered 2kg carbon pellets xx
How about freshwater mussels? Anyone experience with that?
In garden ponds they don’t do really well as they need lots of silt to move around in. We have done a lot in the pass, if you have a clay liner pond then they might do better.
Are there any other algae eating fish apart from Weather Loaches that can go in a wildlife pond permanently, all year round? Thanks
You can’t really have a wildlife pond with fish, it’s a fish pond with wildlife. Wildlife ponds (aquatic insects) should not have fish really.
Having said that I understand some people wish to have a fish pond with wildlife.
I would say depends on the size of the wildlife pond, I have used rudd a few times in large ponds. Small ponds I would say minnows or rock loach, but they don’t eat lots of algae. They prefer to eat the insects and hide in the algae.
@@ThePondAdvisor thanks 👍🙂
How you get the fish that big
Lots of water, lots of food and warmth.
Quickest way to grow pond fish, have an open system, drip water in and let the drip overflow, 10-15% water change daily,
Feed 2 to 3% daily and keep the water up over 60 (14-15oC)
I am about to move my 2 common goldfish from a small indoor tank to a outdoor half whisky barrel pond due to limited space indoors do you have any advice ? Heater,pump,filter etc....
Is the barrel lined with liner? If it’s a reused barrel then you will need an insert to stop the alcohol leaching out in to the water. This time of the year (if your in the UK) will also be a large shock to the fish. You could heat the barrel to 15oC and take it down over a few weeks then next year you will be fine. My biggest concern after the temperature change would be the whiskey
@@ThePondAdvisor yeah I have lined the barrel with pond liner and i have decided I am going to wait until around mid April time to put them into the pond when it is a little warmer
Cheers
Sounds perfect, we had some goldfish in the kitchen we had to upgrade, we missed our time slots last winter so we transferred ours in the late summer this year. They are still doing well, however they are staying way from the others in their little shoal.
I came to see algae eating a pond fish, but it's not as I expected.
Hi Mark, what about string algae and pH Swings. Best live food for koi? Can u do vid on medications? My nephew turned off pump for 2 days. Now the koi are sick. Big one has carp pox. Lost 3 also. Some not eating. I guess stress caused it. I do constant water changes with trickle system. Lots of marginals and big biofiltration. 6000 litre pond. Use pp but how often? Koi flashing still - anchor worm?
MrTruthislight thanks for reaching out, wow that is a lot of question I have noted them down stay turned.
If I were to introduce a weather loach to my pond, then I’d have to put them indoors during the winter? I only have four gold fish in a 1250 litre pond outdoors U.K.
Great question, I have clients that do and don’t personally I don’t keep any outdoors
@@ThePondAdvisor thanks for the quick response. Probably best to stick with albino grass carp then? But I read that they like to jump!
@@JustBaileey yes they love to jump, if you put them in a small pond they will jump, if they are introduced small you are more likely be ok!
@@ThePondAdvisor that’s great to here. Thank you for the advice
Will catfish help keep your pond cleaner ?
Great question, depends on what you class as cleaner, no in regards to clear water: they still produce waste
What fish can I add to my small pond that won't eat tadpoles
minnows
@@ThePondAdvisor ta
Hi, did you take into consideration - Sabanejewia aurata ?
Yes, loach are good at scavenging
@@ThePondAdvisor That specific loach lives in the Balkans. Balkans is the very beginning of the subtropical - meaning it can have really cold winters. That particular loach will probably be able to survive inside a frozen lake, if the depth is bigger than 2 m
Can a weather loach go in a clean, well maintained wildlife pond all year round?
Yes if it’s in your garden with a liner, if it’s an earth in pond no
@@ThePondAdvisor great, thanks 👍 How about a Siamese algae eater/flying fox?🙂🤔
Thanks. My neighbour gave me three Grass Carp about 2 feet long. one of them jumped out and died.
Was the pond smaller? New fish only really jump down to oxygen levels or a smaller space. Some grass carp are jumps like koi, but most of the time it’s to do with the water parameters or some form of irritation
@@ThePondAdvisor thanks for taking the time to answer me
First time on ur channel nd just subscribe it with hit the bell icon to Never ever miss any crazy latest update.....
I have some questions regarding pond ..
1- do u use recycle process after complete the set-up before inviting the fishes???
2- do u change water weekly????
3- do u use heater in Winter????
Plz answer me dear
Do I Cycle the water before adding fish, yes 100% if it’s a brand new pond we add the conditioners and multi aqua and multi clear to cycle or prevent problems down the line. If we have lots of mature pond water we simply pump that in (it’s cycled already), do I do any water changes I have a whole video on do you need to do water changes, quick answer no, do I use a heater in the winter, I live in the midlands zone 7/8 so it does freeze but not that badly an air stone is enough on a fish pond or leaving the filter running. In colder areas turning the filtration of is a good thing and keeping a hole in any ice.

Can I put Zebra nerite algae eating snail in my garden pond cos it ain't big enough for koi carp
I have no experience with such snails.
If they are the same zebra snails in some lakes in the U.K. then I would guess you can keep them in a garden pond.

Jamal Snow I cover this fish the high fin shark in the video, it’s not hardy here in the UK 🇬🇧
Where do you live?
Germany, they sell it as winter hardy a d i have seen proove in the neighborhood, deep pond about 1.9meters
Could there be different kinds of the species? Here they call it "Wimpelkarpfen" or "Fledermausfisch" BatFish^^

What pond fish will eat string algae? Ma ponds looking like the lake in goblet of fire 😂
grass carp
@@ThePondAdvisor what if my ponds only 4000litres.... a pond big enough for grass carp would cost more than the house 😂
Luke Bowler look into treatments and remedies, to lock in the nutrients, stop algae growth, your right 4000 litres is not that big. What fish do you have? Have you seen the video on multi clear?
@@ThePondAdvisor hey thanks for replying, I have a couple little koi and a dozen goldfish, its about 6m by 2m and about 3ftish deep, went away on holiday came back to an explosion of it all
Luke Bowler what filtration do you have, are we talking a traditional fish pond or pool?
What fish can you put in a Fishpond to eat algae?
All of the above, but depending on where you live will determine how long you can keep them in the fish pond.
I wouldn't be putting plecs etc in a pond. You'll never catch them come wintet
Depends on where you live in the world, some people don’t need to catch them.
i prefer to look for mushrooms
Aquatic mushroom’s 🍄?

it was just a joke mate
Hi fin sharks are banned in uk plus they get big
Correct they do not live in the UK in unheated ponds, but I have seen friends across the big pond that keep them, very well all year around.
@Theodore Harrison great comment depending on what temperature your winter goes down to. Or if you heat the pond water to stop it freezing. They are not as hardy as all our ornamental pond fish in the UK 🇬🇧
Any native british algae eaters i can put in a smal tank with a handful of stickies and a gudgeon
No, both these fish will eat the insects that enjoy the algae however.
@@ThePondAdvisor thanks for the reply not sure if you read my comment correctly though
