So my little 55g tank is going to be empty and i was wondering does anyone have any ideas of what fish to keep in there that is pretty hard to get and looks nice. but sorta of a community build of them or so. i got some ideas but i wanna hear some from everyone else please. It has to be able to live in there for a while not just as a grow out tank like i did for some of my pbass and datnoids i had
