Great pics - love your watchman
It looks like it could be a baby bubble coral...possibly.
I can't think if anything else that would have that color under actinic. Or that shape for that matter.
You can get a lot of hitchhikers in on corals. I'm convinced that's where I got a tiny mini carpet. Nice free coral!!
Use/tip a small glass jar setting below where he is so he is able to get in it. Put some sinking pellet food in the bottom of the jar and leave it over night. If he's hungry he will go for it but the glass will keep him from getting back out. You may catch other things as well and there is no garantee this will work but it's a start. Have fun with the hunt!
He doesnt look reef safe Guru....
Im sure youll get more info from others..
Great catch! it doesn't always work. Red eyes and pointy claws are not good as a general rule for our tanks, I'd give him back to the Med. Have fun!
Ok, Just placed the trap.
LOL, half the world wants to wipe you off the map and now some are upset cause you freed a crab. Well done you have my full supoport! Sorry for my jump into politics, it won't happen again LOL.
