I have Otos they are awesome. They do not poo Thant much I don't think of them as really increasing the bio load they do but not like a big snail or Pleco.
The thing with then is they need an established tank. They have a die off period. You can buy 8 and then be left with only one good one that will then live for years. I keep Otos in all my planted tanks. They do best in planted tanks.
Mine keep my tank spotless I have 2 in a 80gal with lots of plants. So they have lots to graze on. They don't really school. but do enjoy being around thier own kind.
I love Otos try to buy Otos that have been in the tanks for more then a week. The bigger the better. Fresh imported Otos are the ones that die off. I bought 8 from petsmart and only one lived. I bought 2 larger ones that had been at a Lfs for a long time. They did great in my tank and are still going strong.
I would never buy Otos from petsmart.
100Gal Cichlid tank, 80 Gal planted Community, 20Gal planted Betta, 7gal planted Betta, 20gal goldfish grow out. Yeah I like fish.
