    Hi Werner,

    Not very clear from the pic , but does it look like a perforated calcerous structure ?

    If so , these are a type of Bryozoan - Iodyctium Sanguineum (see pic below). Unfortunately , they don't do well in our tanks at all . I have quite a few of these on my LR , but they have all turned white . They are normally bright purple, red or light blue in colour

    Yes Werner. It is. It could be terrible for your fish (they kill fish while sleeping) - VERY bad for your inverts (they eat and kill starfish, as well as snails).....

    No I dont think he would.BUT,I say that with caution,with crabs you just never know.They are scavengers and opportunists mostly.To them an easy meal is an easy meal,whatever it is.Rule of thumb......get rid of the crab!!!!;)
