The Coris wrasse is still a pretty small juvenile, maybe 1 1/2" or 2", and he doesn't seem to bother anyone, there's plenty of turbo snails that are doing fine as well as little nassarius snails. The only shrimp I have right now is a coral banded, and I'm not really in the market for any more b/c I think the dwarf lion would eat them pretty quickly. I don't have any zoos or LPS besides the euphyllia, and the koran doesn't bother it at all.
I don't know if I'll upgrade the tank, if I do it's a long ways away!
