Hey! I was looking into getting a some fish but I want to be really educated on the fish I'm interested in before I buy them. So I was interested in some bettas, Cory catfish, ghost shrimp, and some kind of snail. I was wondering if I can house a female betta with 2 Cory catfish, a few ghost shrimp and snails, if these all can be housed together what would be the minimum size tank gallon? also, what other animals would you recommend?
