I've got a 6gal aquarium with 2 algae eating shrimp and a betta named Fibi.
I was thinking of adding 2 oto cats, since they seem peaceful enough to get along with Fibi. Is my aquarium big enough for 2 otos? I've been reading a lot about them, so I know they don't like to be alone, and I'll be feeding them algae wafers. My betta gets along fine with the shrimp, I just don't want to upset anything if otos are not really compatible, nor do I want to crowd the aquarium. Also, I'm concerned about how 'fragile' they seem to be from reading other posts.
