Hello I recently picked up a 125gallon and need help with stock ideas. I definelty want a poly but I'm not sure what kind. I don't want to upgrade too too much most likely nothing more than another 100 gallons. So I don't want anything that gets CRAZY huge but I do want one that will reach a decent size. Also one that is has nice colors so give me suggestions! I also want more fish to go along with him/her. Are they better to keep with pairs. And what fish could tank with it. I do like "different" fish like oddballs and what not but am open to any suggestions. Thanks!
