I have one, but he's destined for a larger Reef ( at least that was the plan, before I lost my stinking job! GRRRRRRRGGGHH) soo.
Will root in LR & overturn frags not glued down. Otherwise, safe with coral. Young ones not too bad socially, large ones fit for Aggressive tanks only. Hyperactive, & strong food competitor, too. Don't house with slow, shy fish!!!
