i have 2 tanks. One tank had 2 male mollies and one female along with some tetras and guppies. I now know that wasnāt the best. One male long fin mollie was nipping at the other male mollie really bad. His fins are split and we didnāt think he was going to make it. We decided it might be best to get the dominant male out of there, so we moved him to our 20 gallon tank. That tank has 1 good size neon rosey barb, 1 tiger barb, and 1 albino tiger barb. The barbs are nipping at the mollie. Not terrible, but quite often. Do you think I can make this 20 gallon arrangement work if I add a couple female mollies?
