All of my Oto’s are on the round side, but i noticed today that one of them has suddenly ballooned. Im hoping that shes a female packed full of eggs because i would love for them to breed!

Have any of you bred Oto’s succesfully? And if so do you have any tips? Its my understanding that they dont breed in captivity very often. Ive tried searching for info about breeding them but it seems like theres really not much out there. Does anyone have any info on why no one seems to be breeding them?

So I was successfully spawning the black otto's a while back, see the video above. I found the biggest key was to have a fat and happy female. This of course involved feeding the oto's and not just having them forage for leftovers. I did colony or group spawning in a 10 gallon tank and found that it was very similar to corydoras spawning. Once well fed, did a cool water change at night and was rewarded the next morning with eggs all over the glass, plant leaves, etc. I rolled the eggs off with my finger and put them in a tumbler where they hatched in a few days. Right from the start they fed on live baby brine shrimp and Sera Micron. Growth was about the same as corydoras fry.

What's a good food for otos? I've been feeding them repashy super green (not soilent green, don't know the full differences). I also have the hikari algae wafers that I put in a lot of tanks. 


when I had the black otos breeding I was frozen brine shrimp, zucchini, green beans (from a can), as well as the algae wafers.

Got lucky with Otos as well. Had about 40 fry all over my glass. But I only see about 20 now actively swimming.  I followed Dean's advice and so far so good. They seem happy. The last pic is when I  first notice these little transparent things on my glass. The other 2 pics was today about a week and half old now.

Thanks @MickS77and @Dean’s Fishroom for the info. It makes sense to me that breeding them would be similar to corydoras because they school with my julii corys alot and even eat their food regularly. My Corys just spawned for the first time so hopefully Oto’s are next. Ive been feeding italian zuchini, sweet potato, cucumber, repashy community. My Oto’s wont touch the algae wafers tho for some reason.

My Otos love veggies. I peel strips off of zuchini, sweet potato or cucumber and i microwave one piece for a few seconds to soften it and hang it from the side of the glass with a suction cup clip. They didnt know what to make of it the first couple times i tried it so you may have to be patient. Now they chow down on that stuff till they look like little balloons. Mine also munch down on meaty sinking pellets from time to time.

I woke to some crazy oto activities one morning. I think they were breeding. I took some video i wish i could share. I tried to google oto breeding and didn't find any video of them in the act. The male wraps its self around the females head. its rather crazy. here is a still shot of my plump happy female and the 2nd is what i think is otos in the act.

I could be wrong but i think that what i got on video. if there is a way to share the video id be happy too. i just don't know how.

Zucchini, Cucumber, Repashy Super Green , Spinach, and whatever Algae grows in the tank. There looking healthy.  I cut slices of cucumber or zucchini and use the extra airline holder suction cups. Push the cucumber on and place on the side of the glass.  Spinach i just stick the stem in the gravel . Not all at once. I switch it up every other day.  I usually leave it in for 24hrs. Then I remove before it makes a mess.

https://youtu.be/u7mtr7ru9V8  OK never posted to you-tube, hope this works

 

“Oto’s Gone Wild” LOL I love the title. Thanks for posting the vid @Dave23. Definitely looks like some spawning to me. That head wrap move is pretty crazy, but i guess its sorta like the T shape move Corys are supposed to do.

I put a lil bit of water in a small plastic container, put in microwave for 30 sec to a 1min. Take out once done and i let the Spinach sit in the hot water for 2 min. Let it cool off and it take a while before they notice its there. But after a hour or two,  I always find a few on the the Spinach.
