Hi everyone! I have a new 10 gal tank with 3 female platy. I was really interested about possibly getting a couple more fish that would eat the same food. I want to follow the 1 gal per inch of fish, so having 3 platy that could grow 2 in, I have about 4 in left to fill up. Its a tropical tank with a few fake plants and sharp largish rocks, so no corries. Any suggestions?-thanx!
