I have a betta (I think a half moon) in a planted 15 gallon tank, but instead of being more elongated it has a square-ish shape (it's the 15g Fluval Flex). other than the betta, I spotted pond snails and MTS that came with the plants, which I don't mind having. I want to add other tank mates, but not sure which one would work in that set up. I was considering 3 or 4 Pygmy Corys but my LFS doesn't have any in stalk. any ideas for a substitute? I was told 3 or 4 Panda Corys could work, but I know they would be happier in a larger group.
(also, don't mind his fins in this picture. He used to have fin rot, but isn't very good at growing his fins back.)
