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

 

[werner5]

thanx for all the info guys

hey i found this crab on the live rock also what type of crab is it

 

[Warr7207]

That is a gorilla crab, not good. Send him to a mantis owner like me

 

[leslie hempel]

i would kill for a piece of LR that richly couloured in corraline right now.. .

 

[werner5]

i got the LR from my lfs and then it was already couloured with corraline

As Warr said - gorrila crab - more scientific name: xanthid species crab.....

 

[dallasg]

damn Warr, beat me again

 

[jacquesb]

It seems that Warr actually HAD LESS WORK to do than you Dallas! LOL!

Is A Gorilla Crab Bad

 

[jacquesb]

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).....

Is A Gorilla Crab Bad

Well that depends......If you dont like corals,then NO ,he is an asset to have!

 

[werner5]

will he kill the cleaner shrimp

 

[goodisor]

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!!!!
