I love mine, he is really curious and friendly, they will eat ANY and ALL shrimps, and attempt to eat other inverts. If he is hungry and I am working in the tank either he nips. Other than that he gets along with my flame, false percs, and my bangaii cardinals. I think he ate all but one of my bangaii babies. He dosent pick on my corals either. He does eat nori though, kinda wierd.
