I just saw this guy munching through half a dozen polyps!


He arrived on another rock that was purchased covered in polyps peering out of a cave -


I think....


The mystery crab seemed very white in the beginning before disappearing, molting once and then reappearing [?] This one is of course brownish in colour, but a very similar shape and size - can crabs change their colours as they mature?? SIZE: 1cm across carpace.


Didnt see him actually eat the polyps but its a case of now you see me now you dont as within 5mins of me not being there the polpys were not there! Perhaps its a case of unfair justice that he was merely 'seen' in the vicinity but hell, im not taking any chances!!!


I also noticed tear-marks in the mat of a large colony of polyps nearby...

Do you know what color ikts claws are? I found a very similar looking crab hiding in a cave near some zo's as well, it was white with black claws. I have a feeling the guy was eating my zoanthids.

I dip my zoos in fresh RO water for a couple minutes...It cool cause all crabs, shrimp, starfish, pods leave the rock and go to the bottom of the container they are in and you can see what was on the rock that you didnt want in your tank...

My brother had that exact crab in his tank, and it was eating a huge amount of our zoas, palys. We actually saw it rip off a paly, and begin to eat it. Deffinetly a bad crab. It has a striped pattern on it's legs, and black marks on the top, right?

Took some shrimp, a fishing hook, and we got him.

get rid of it. I had one in my 60g one time that starteed that size (knew this because of the moltings), but could never catch it. By the time I did, a year later, I had lost a bunch of zoos, a clam, and a few others, and it was close to 2 inchs in diameter. Im freaked of hitchikers now.

Well i dont believe the crab should die. but i guess people will be people. i usally just find a lil tank for them & let them battle the other hitch hikers for food. its more intresting that just squashing them with a hammer. though i have been wrong before? LOL
