I had 3 blue gouramis in my 20g and i decided to bring 2 back to my LFS so that i had more room for danios and such (as i have 3 and need at least 2 more for a healthier school) but what else should i get?
5 albino corys
1 blue gourami (after i ditch the other 2)
3 purple danios
5 albino corys
1 blue gourami (after i ditch the other 2)
3 purple danios
OR you can get 5 guppies. Guppies make pretty schools. (They're awesome litttle fish!!!) That would be a total of 14 fish. I think that's all your 20 gallon can handle, I wouldn't get anymore than that if I were you.
