that thing looks mean. deffinate sump bound, or mantis food???

hairy, red eyes, black sharp tipped claws. that is the definition of a bad crab. to the sump he goes... unless you know someone with an octopus or a mantis shrimp :)

well that's not a nice looking little bugger.

But fwiw, there are such things as "marine spiders"...they're disgusting.

hey pycnogonids are awesome! they just *suck* when they're sucking the juices out of your corals in a mosquito like fashion...

I sort of figured there were marine spiders! I was 99.9% sure it was a crab but when all I ever saw of it was 4 hairy legs curling in and out of a hole in a rock. You never know.
There might be a guy coming over today with some coralline scrapings for me he has a mantis problem. I will probably give it to him. Unless you can catch it Rob, I would set up a 10g for it!
For my next seek and capture mission, the 10" bristle worm that I finally saw in full last night.

hunting bristleworms is a lot more trouble than it's worth. unless you actually see it eating coral, it's harmless. the coral eaters are very rare.
