Any chance that my nephthia got chomped by a hermit crab in my 10 fusion?...he doesn't look so good and seems there is a piece missing at base of the "trunk"...also had a hammer coral near him, but this looks more like a wound...anything to help him?...should I lose the hermits?...I know that Albert J. Thiel feels that they're not worth the risk...others disagree...My poor neon green nephthia!
