Oto behavior ... normal or not?
I have 2 Otocinclus that I have managed to keep alive and well for several weeks now. They seem to like swiming in large vertical orals near the back of the tank, zipping around one after the other. I was wondering if this is normal behavior? They didn't look this active in the petstore tank. And sometimes my betta goes back and swims with them - not attacking or anything, just kinda schooling with them. So I just want to know if this is normal Oto behavior, and does it mean something? I want to make sure I'm not doing something wrong.
