Black and White Crab, friend or foe?

Found a Black and White crab. To fast, did not have a chance to get a camera.

How did it look? Was the body white and did it have a black stripe across its face? If so it may be an acro crab, but I can't be sure without a pic.

White body, black patches/dot, not sure if there is a black stripe across its face. Seems able to do aquascaping

xanthidae

Maybe this will help

crab cakes anyone?
better safe than sorry IMO

 

[reefman]

hairy? no good.

Closest match is Xanthias punctatus Guam 401-4

but still quite different. So hard to take a naked pic of that sleeky guy/girl.

FOE!!!

say good bye to any zoo's I had one just like it ate a Rose BTA
set a trap and catch it!

Last week I spent several hours taking out most of my live rock to get to a Zosimus aeneus which is a member of the Xanthidae family. This monster was eating all of my Zoanthids as NYPDFrogman mentions, and knocking all of my corals off the rocks, even the epoxied ones! Here is a close pic of the monster I captured, my son brought him to the LFS as he knew I would skewer it.

that could have explained why I have a sabae anemone torn into two piece(leg and the crown:lobster: :eat: ) and some zoe clony polyps disappearing.

looks like my rock tank got another convict

get a mason's jar ( glass jar used for preservatives) take a plastic soda bottle cut the top 3" off invert the cut portion of the soda bottle into the mason jar take the lid out of the cap and screw the cap onto the jar securing the cut bottle in the jar
put a nice size piece of food in the jar submerge it and wait
works great right after the lights go out.

easiest way to catch the bugger

PS the cut part of soda bottle that goes into the jar is the part in which the cap screws on LOL leave the cap off

Just discovered I have a big one of these zoo eating,
rock moving xanthidae crabs in my 24g.

What's a good piece of bait to use to catch
this mofo?

What do I do with it once its out? Skewer?

Thanks

Use Zoas.

Freezing is more humane

I'll freeze him in exchange for a serious answer.

 

[Chiefmcfuz]

That was serious.

If it is eating zoas put some in a glass jar and hope he goes for them. Or you could try other bait if you want.

Freezing pests is more humane than killing them.

 

[mstrofdisaster]

Ok, thanks. Just a little stressed out with this problem.

Just wanted to know if something like mysis would
be good enough. But since they eat crap all day I guess
anything would be good.

BTW, it's more than one year now and the two are transferred from the maximum security "The Rock" to the new rock pool and they both get bigger. Your pseudochromis is a die hard hardy fish.
