Definite crowd pleaser. But useless, for everything other than the crab that lives on him. Now, he's as cool as anything I've ever had in my tank, almost makes it worth having a nem. The clowns don't host him or the GBTA. Just spreads out wide, walks over other corals, and generally stresses me out. Maybe he is walking to split, I've never seen it do that yet in the past 4 months. Hopefully I'll be able to isolate one or two or all of them and give them up for adoption.
Good news is that he's past over a zoa colony and they are alive and out. No damage at all. Headed towards a hairy neon green mushroom he can take out if he wants since it grows rampant in my tank.
