I had considered that. It was oginally going to be a betta tank, then I considered a cobalt gourami since I really like the look of them, but didn't think 7 gallons was enough for it. Also wasn't sure about keeping a single one as opposed to a group and I knew I woudl really be pushing it with a group of them in a 7 gallon. I'll probably end up with cherry shrimp in the tank as they are kind of cool to watch, although if I do end up with a betta it's usually only a matter of time before the shrimp end up as lunch. I have a few tanks at home that have some really nice cardinals, and some endlers I got a great deal on at one point, and some white clouds. I started wondering if a small school of small fish would be better than a single larger fish. I've kept endlers with a betta before and most of them did ok. Either way I thought I would come out and see what you guys thought. You never know when someone will come up with something that never occurred to you before....
