Hi mark ive recently mooved to a boarding school and done my first nano aquarium with an amazing aquascape in school its so much more less boring now 😂. Your vids are great and inspiring.
love ottos! cool looking and super chill fish that help balance and clean a community tank. great fish. thanks, mark! looking forward to another video!
Wow thats beautiful. I got 8 in a planted 300 liter tank with tetras. Don't see them too often unless they come out and sit on leaves of plants at front. Or I turn on room light at night. Lovely little fish. 👍👍
I hope I can meet you one day @marks aquatics you have taught me so much and have been my inspiration from day one. I really appreciate all of your hard passionate work you put into this hobby and TH-cam. Thank you
How is it going Mark :) Hope you and your fishes are all good. I would love to see one of your old school videos again. You know, diy, guppies and swordtails ;)
One of my favourite fish well done its so nice to see that it can be done if only more people could then less could be taken from the wild . I personally would love to see you breed khuli loaches if it's at all possible .look forward to an update when they get a bit bigger thank you for taking the time to share your success xx
Hi Mark, sorry to jump in on the comments section regaring something a bit off topic, however I'm looking for expert advise on controlling a nitrite spike (max reading has been 1.5ppm). 5 days ago I purchased some longtail Panda Corys which unfortunately developed finrot after 48 hours. Within 2-3 days 1 had died, the 2nd died approx 12 hours later, the 3rd was returned to the fish store who were already aware as they have had several reports of the same thing with this particular batch of fish. The issue is that the dead fish was totally hidden away rotting in my tank for around 2 days (unable to find it until today!), and I stated to notice a few Cardinals were surface breathing and my water was clouding up. I treated my tank with finrot treament (half dosage) proir to the clouding then also discovered that the Nitrite had started to rise from zero (I perform daily water tests for 3 days when introducing new fish), however at no point has my Ammonia been anything but zero - which my specialist fish store confirmed on a sample I took in. I started with a 30-35% water change (Nitrites then reduced from 1.0 to 0.5ppm) but within a few hours when I did my next Nitrite test it had gone up to around 1.0ppm again. So I repeated with another 25% change (each time treating the tap water with API quick start to remove the chlorine), however after a few hours again the Nitrite climbed up to 1.0-1.25. I then stayed up all night monitoring the Nitrites every hour, performing another 30-35% water change at 3am this morning, by 7am my Nitrites were 1.5ppm and the fish are stressed out. At this point I've performed 5 partial water changes and the Nitrites keep creeping up and I'm very worried because I have 3 rare plecs and no spare tanks or spare cycled media to combat the bacterial bloom...2 Cardinals and a Glowlight Danio have died so far* Speaking to a local expert he has advised not to treat my tank with Prime (water conditioner) and a new bottle has just been delivered by Amazon - do I treat the Nitrite directly with the conditioner or as I've been advised, will this potentialy put me in a worse position by increasing the toxicity threshold of the water? My water is still cloudy, still around 1.0ppm Nitrite / 0 Ammonia, Nitrates are approx 0.5ppm in a heavily planted 400L tank. My head is telling me to treat the tank with Prime because the fish cannot sustain this for long and I have 3 rare & expensive Plecs that I'm terrified about losing. Please help me :(
Hi Mark I've followed your channel for some time now and I wondered what you use, if anything underneath your tanks to cushion them against uneven surfaces, etc. Regards Ian
Mark you make it look so easy! You've only just started this project and it's already taking off! Do you have any tips for foraging sources of infusoria, copepods and such to add to a tank?
Hi I don’t know if you can help me but I bought a pair of clowns 1 week ago, added them to quarantine treated for internal parasites and after a couple of days they were eating, doing 10 percent or less water changes every other day and then when I did a larger water change and added 2nd treatment last night, they have stopped eating today... acting normal swimming but look a little scared and stressed, maybe because of the treatment and heavy water change they are stressed? Any ideas?
Quick question to Marks aquatics I just purchased 5 otocinclus catfish, They don’t want the algae wafers I’m trying to feed them, What should I feed them? Also great video eventually I’ll try and breed some 😊
I second the zuchinni although I dont blanch them I just weight them down with a rubber band and a rock. I always make sure my herbivorous fish have some zuchinni, yellow squash, leaf lettuce for them to eat
Sometimes it takes a day or 2 before they start to eat food they don't know yet. So the wafers might still work once they know it. I have most succes with a slice of cucumber but again it might take a day or 2 before they really start on it to eat. And peppers like Mark said are also good.
I’ve one of the fattest lil fatty arbuckle female ottos I’ve seen, plus 2 or 3 lads. Now would she probably be laying eggs in the Kubotai tank and maybe they’re just getting eaten or what not OR are they too hesitant n scared to lay in a busier tank? I could remove the, into a diff tank for few weeks to see? Have you don’t Borneo Sucker/Hillstream loach breeding? I’d luv to see you do the striped Borneo suckers. THEN I can learn n have a go 😉🤪😁💙
hi Mark how do you get clean water for water changes for years I've been filling a few 20Ltr drums from the tap adding pond declorinator and a air stone and leaving it min 2h max 4days it's not working for me any more I live in NW pennies and they are using chloride now not chlorine and I think the declorinator is converting the chloride to ammonia I need to figure out what to do over the last 2 years I've had so many tanks crash and lost a lot of fish I have been close to giving in I've all ways gone with if something seems wrong in a tank do a few big water changes but if the new water smells like cat pee what do you do😥
Very late to the vid , I love ottos , I found the recent cory fry ( happy little accident ) I had loved to sit and feast on that same sponge you have on inlet it was crazy seeing them all useing as a bunch of shelves
Awesome video. Thank you so much for the series…I really enjoyed it. Recommend Denison barb for your next project. I hear they are impossible, but I recently saw two stores selling tank raised ones.
Im in the process of setting up a small fish room to breed my2 favourite fish, chili rasbora and galaxys! your videos have been very inspiring. You are a wealth of knowledge for us and we all appreciate you making these videos. Can I ask any tips for keeping your fish room? I have an outside shed thats enclosed but do you heat your shed or just the tanks? Ob viously were both similar climates so wondering whats most effective
So happy when I saw that this video was just posted!!!
Hi mark ive recently mooved to a boarding school and done my first nano aquarium with an amazing aquascape in school its so much more less boring now 😂. Your vids are great and inspiring.
Wonderful series! I've loved otos for decades, but never thought breeding them at home was possible. Thanks so much for showing us how to breed them.
Well done Mark, i have posted this video on my Otocinclus Catfish Group on Facebook, i hope it helps the followers.
Hill-stream Loaches would be fun to watch grow as they change shape so much.
Same for Corydoras. However, this Oto breeding series is far more interesting!
Thank you for keeping us updated.
I hope you will post their progress with us please. 😊
love ottos! cool looking and super chill fish that help balance and clean a community tank. great fish. thanks, mark! looking forward to another video!
Always good to see some wrigglers. I still get delighted when I see live bearer fry never mind egg layers. Great job Mark 👍
Wow thats beautiful. I got 8 in a planted 300 liter tank with tetras. Don't see them too often unless they come out and sit on leaves of plants at front. Or I turn on room light at night. Lovely little fish. 👍👍
Great videos mate, straight talking no messing and making it look easy 👏
Just another amazing project and as always completed with a big success. Very nice videos you are making Mark, keep it up!
Mark, why have you stopped posting? When I first started breeding fish you were my guiding light!
Sadly the electricity bill got so high I had to really down size . Hopefully get going again soon.
Impressive! Never tried but I always thought Otos would be harder to breed... Or maybe you're just brilliant at it :)
Is there a part 4? How well did they grow up?
I hope I can meet you one day @marks aquatics you have taught me so much and have been my inspiration from day one. I really appreciate all of your hard passionate work you put into this hobby and TH-cam. Thank you
Thanks for watching 🎅👍
Good Job, great little series.
How is it going Mark :) Hope you and your fishes are all good. I would love to see one of your old school videos again. You know, diy, guppies and swordtails ;)
Aaand... he's back! Lovely vid yet again.
One of my favourite fish well done its so nice to see that it can be done if only more people could then less could be taken from the wild . I personally would love to see you breed khuli loaches if it's at all possible .look forward to an update when they get a bit bigger thank you for taking the time to share your success xx
woop woop, well done mark!!
Can't wait to watch this when I get home n get in my jammies
Did the fry survive? Seems like people are able to get the otos to spawn, but raising the fry is that hard part.
Would like these to start becoming a tank bred species. They'd be less fussy eaters no doubt, if raised on a commercial fish food diet.
Great to see them hatching!!!!!! K
Amazing Mark, thank you!
Awesome Mark 💕

it's been 4 months now , have they survived?
any more native aquarium vids on the horizon?
Probably next spring now.
Hi Mark
I've followed your channel for some time now and I wondered what you use, if anything underneath your tanks to cushion them against uneven surfaces, etc.

Ian
Hi. I use underlay for under wooden floors.
Mark you make it look so easy! You've only just started this project and it's already taking off!
Do you have any tips for foraging sources of infusoria, copepods and such to add to a tank?
cheers for update
Amazing video Mark really exciting!
Are you planning on selling your little vegetable holders I’d love to get one?
You are a phenomenal fish breeder Mark, is there any fish you've had difficulty trying to breed?
Hi Mark, beautiful what yo have done with these otos. I'd like to know the kh and gh of this tank ?
Hey Mark I've lost you on fb....don't know how that happened hope your well.
Hope all is well, noticed you haven’t posted in 2 months.
after watching this I have just got 6 otos
If you want a challenge try breeding African butterfly fish an amazing fish with unique behavior
Mark! Where are you? It’s been a month since this video. Need some welsh aquarium updates. I hope you are well.
been a while since you last posted,, hope everything is ok. looking forward to an update.
Happy New Year Mark!! Hope your okay! hoggie UKaps.
Did you remove the adults?
Hi I don’t know if you can help me but I bought a pair of clowns 1 week ago, added them to quarantine treated for internal parasites and after a couple of days they were eating, doing 10 percent or less water changes every other day and then when I did a larger water change and added 2nd treatment last night, they have stopped eating today... acting normal swimming but look a little scared and stressed, maybe because of the treatment and heavy water change they are stressed? Any ideas?
Did you leave thd adults in the tank? How did they do?
Mark how is the tank fund going? Are you willing to give an update on it?
Another whole month has passed... please update good news bad news ..ANY NEWS please I'm constantly checking lol
Hi hope your ok haven't seen any. New videos for a while
Hi Mark - been over a month I think since we got this last video - are you well??? Hope that everything is ok at your end......K
Is there any fish that won't breed for you? Lol. Amazing 👍
The oto's whats?
Hi. You still here mate?
So did they make it to adulthood?
Yes they sure did. Thanks for watching
💖👍🏻
Quick question to Marks aquatics
I just purchased 5 otocinclus catfish, They don’t want the algae wafers I’m trying to feed them,
What should I feed them?
Also great video eventually I’ll try and breed some 😊
Try blanched zucchini, make sure to take uneaten out after a day, also having lots of natural algae build ups in the tank helps
I second the zuchinni although I dont blanch them I just weight them down with a rubber band and a rock. I always make sure my herbivorous fish have some zuchinni, yellow squash, leaf lettuce for them to eat
Sometimes it takes a day or 2 before they start to eat food they don't know yet. So the wafers might still work once they know it. I have most succes with a slice of cucumber but again it might take a day or 2 before they really start on it to eat. And peppers like Mark said are also good.
Spiralina tablets, bacter ae, bell pepper, Indian almond leaves
Where is Mark?
Are they still alive, and if ...how big are they now ?
When is the update???? I've put my TH-cam notifications on just to see your update
Mark? Hello mark? It’s been 2 months my friend. I hope you are well and just too busy for videos.
Nice update. How many are there?
About 6 🎅👍
I’ve one of the fattest lil fatty arbuckle female ottos I’ve seen, plus 2 or 3 lads.

Thank you documenting this! Love seeing how they progress :)
Nice video Mark. Next fish to breed Nannostomus mortenthaleri.
I' m breeding them succesfully.
Hey Mark, its 2022 Haven't heard from you this bew year yet. Hoping you are well. Hope to hear from you soon.
I enjoy watching the videos you make...
Wow. Congrats mark…they are really jittery swimmin lil guys aren’t they…
Congratulations Mark, another fantastic success, gg. Have you ever tried to breed Bumblebee Gobys?
Fantastic!!! i hope you're going to breed pangio some day!
well done sir great to what thank you 👍👍👍👍
Very late to the vid , I love ottos , I found the recent cory fry ( happy little accident ) I had loved to sit and feast on that same sponge you have on inlet it was crazy seeing them all useing as a bunch of shelves
Brilliant. I am a huge fan of your work. Did you remove the adults?
Hi Mark, is true that you use Dr Novak's method of the anoxic filtration and that you are happy with the results? Keep up the great vids.
You're always successful at breeding the more difficult fish, and I always learn tips, and tricks from you. Thank you for sharing your knowledge.
👍❤👍
absolutely amazing Mark 👏
Awesome video. Thank you so much for the series…I really enjoyed it. Recommend Denison barb for your next project. I hear they are impossible, but I recently saw two stores selling tank raised ones.

I have an outside shed thats enclosed but do you heat your shed or just the tanks? Ob viously were both similar climates so wondering whats most effective
Captive bred ottos!!! Keep up the good work!
Brillian stuff , it seems you get most fish to breed Mark.
Haven't seen a video in awhile. Hope everything is OK. Prayers to you and your family
All ok. Just had a break from it all.
Don't blame you. Just know you are missed.
