Hi everyone! I'm still cycling but went to look at fish today to try and make a decision. Never would I have thought, but I saw the most beautiful balloon belly Mollie. It was such a pretty deep yellow on the top and pearl irridescent on the bottom and shaped almost like a little bouncy ball. I fell in love but couldn't bring it home. Is a 29 gallon big enough to have one of these? Should I have more than one? Thanks all
