ID, anyone?

well i would think its a rock crab its found mostly on live rock hitch hiker. im sure there are those who know. As for me I think its cute .. I would put it in a QT until you know what it is. some have been known to eat coral & fish.

Yeah, I like it too. I'm not going to thrash it, but house it in a compartment of my "bates motel" of weirdos to come.

"Rock crab", huh? Anyone know any more specific...?

red eyed xanthid crab. common hitchhiker on fiji live rock. not reef safe at all and it will kill your fish. i keep mine in my sump/refugium. pretty interesting to watch, but toxic so watch your fingers!!

how'd you catch it?. I have one and want it out.

Dreamersdisease, thank You for the ID.

I suppose Bali is close enough to Fiji, that's where my LR came from.

Mini_GBR: Well I found catching it actually quite a pain...

For about a month I tried various sophisticated baited crabtraps, to no succes. I actually started to believe that the crab is not interested in shrimp, fish or any other meaty food. It was more interested in just fiddling with rock than the baits right next to it.

In the end I just went medieval on it's ass and waited for it to come out of hiding at night and caught it with a net.

oic, so nothin fancy then. But you saw this crab on numerous occasions befre actually getting it. I found a molt of only the pincher, so I think I have one. I can't tell though, and I can't figure out how to know if I have one or not.

Yes, I did see it almost every night and sometimes during the day, 'cause it chose to call quite a big hole in the rock it's home.

Also, I'm actually half way there at this point, becouse there is another, smaller crab (similar to this) in my nano.

And I do see your problem, I've only seen this other guy a few times. I think I will catch it when I upgrade the nano in the not so distant future.

We just ended up waiting until it crawled into a rock, pulled the whole rock out of the tank and pried it out with some dentist tooth pickers

Sounds like a very smart thing to do, whenever you actually see the crab.
