Hello Fellow Fishlorians! I got a free 2.5 gallon tank! What kinds of killifish should I stock it with? I want non-annual killifish. The one that I want the most is the Simpsonichthys santanae, but it's annual. I know that clown killifish aren't annual, but I want something else. Pupfish or toothcarp species would work too. If you don't know any killifish species to recommend, any other recommendations are welcome.
