I have a 3 1/2 month old fry that I think is a balloon belly; about a 1 1/4" long. Now that I have her in a 10 gallon, I want to get her some friends. Keep in mind that she's still pretty tiny, so at least for a while I want to get some fish that are similar in size. I'm thinking some of the dwarf coral platies or these fish I just saw tonight called Orange Flame Rio Tetras. I eventually will want to add another balloon belly, but when she's bigger. For now, how many of the smaller fish should I add? Suggestions? Thanks!
