I have two neon dottybacks. One lives in a 14 gallon with a peppermint shrimp. The other was in my 72 which had an aptasia problem. I threw 8 peppermints in there and watched him chase down and eat 4 of them within a couple of minutes. He would just swim around with one stuck in his mouth. It was horrible to watch as they tried to get away. Now, he is alone in my frag tank, yet the other dottyback is fine with his shrimp friend in the 14. Go figure.
