Hi there, Im new to the fish world so please forgive any ignorance because Im still learning. I currently have a 20 gallon tank with only 1 red zebra who is maybe midway through his growth cycle. He had another tankmember (another red zebra) who he liked to chase. So basically he's not as aggressive as I've heard most cichlids are but he's not very nice either.
What I need help with is I'd like to make my tank more interesting with more tankmates if possible. I'd like to get other than a red zebra but thats pretty much my only prefference, just something live and different (fish, crabs, crawfish, etc.). Im not able to get a larger tank so a 20 is all I've got. I've done research and haven't really found anything yet so Im hoping somebody can help. Thanks!
