Advertisement I just got a beautiful new super delta betta, and I want to set up a small tank for him. Right now, he's in a bowl, which I'm feeling a little guilty about. I know people that have had bettas live for years (and, apparently, thrive) housed this way, but I've been doing some research and it seems that they ideally need a five-gallon tank. I'm working on getting that going, or maybe something slightly smaller (it'll have a filter, and if it's less than five gallons I'll just do water changes more often). Anyhow, I was just curious -- what other animals (fish, inverts, etc) could I keep with him, if any? I was thinking perhaps a snail or a dwarf frog, or both. Another thing: he'll be okay without a heater provided room temperature stays at 70º+, correct? Thanks in advance!
