Same boat here...looking at maybe a Copperband. I just bought a 120g that I'm upgrading to, but I've still got quite a few Aip in the rock I'll be transferring over. Can't do Peppermints since I have a Marine Betta and Dwarf Zebra Lion...unless I move those fish to another tank temporarily.
Do Copperbands nip at corals or clams?
