I read the article on oto cats in Shanes World on the oto's & I would like some opinions on what to do. I have 2 tanks availeable.A 10 gal.& a35gal. The 10 gal is a bare tank with box filter & floating hornwort.The 35 gal. is graveled with lots of low caves,sword plants & floating hornwort.The 35 is also loaded with brown algae. The article said to breed them a small tank is best.It also said brown algae is a great food to help keep them healthy.What I would like to know is which setup would be best? I do want to breed them.Also what #'s would be good for the 10 or 35 setup?
Would it be an idea to condition them in the 35 & then move them to the 10 for breeding? Or stick to 1 tank for the duration?

Hey,

please take a look on this and this two topics.

After you read them you will notice this two topics say about cory breeding together with otos :) and this could be a trigger!

I would personally choose a 35gal it looks like a better home for otos.

Regards.

I can't see any reason why a 35g tank would not be better than a 10g tank.

Larger tanks are always better than smaller tanks as they offer greater stability of water conditions and a greater margin for error as pollutants will build up slower.

Also you can keep more otos in a bigger tank, so you'll probably have a better chance of success.

How about approx 20 otos along with some sympatric corydoras.

I would go with the 35g, especially as it has lots of delicious brown algae

Try a forum search and there should be a fair amount of info on breeding otos.

Good luck with your project.

Thanks for the good advice on the oto's.I have never heard of using corys to induce the spawning.I think that is what I will try.In order to do this how many corys should be put in with how many oto's? I will take the advice & use the 35 gal. tank.
