Please give me some fish that I can put in with my cory in a 10 gallon tank, I am taking back my molly tonight so I can put some thing eles in the tank.
Also I'd get at least one more cory, depending on how chunky those emeralds get. They'll be the main consideration w/ your bioload; the harleys are so small, as long as you're not tempted to overfeed, and you get a small school.
