I have recently bought a 30l tank (rectangular shape but with rounded edges on the front) and I haven't set it up yet. I am thinking about getting some tankmates to go with the Betta in there and was wondering if you had any ideas? At the moment, I'm considering getting a few Ember Tetras and possibly a couple of Otos. Would these fish be suitable or are there better tankmates?
I've never really been a fan of shrimp, they kind of creep me out. Ember Tetras are really tiny so I don't think they would have much of a bioload, but then again, Tetras are only effective when in schools in a larger tank. Are there any other fish you would recommend? What about Corydoras?
