I have a 125 reef tank that has been setup for 2 months. I added 80 lbs of live rock that had all kinds of life on it, but I didn't notice anything large scale until now. Sorry, I was not able to get a suitable pic due to the LED
lighting that I use. I noticed a new crab, about the size of my arco crab (3/4 in leg to leg) or so. Its legs are hairy and shell has lots of small bumps. I know its not big enough to do much damage, but also hairy legged crabs are generally bad for the tank.
So, any idea what it is? And, even if I determine it to be unwanted, how in the heck do I catch it?
