??? It's clear with arms

[ljp3]

I found two of these last night, and today those two were gone and I found three today.

These are clear with a fat trunk and clear tenticle-like appendages andare about an inch to 1 1/2 inches long. I attached a picture but it isn't the greatest. Any help would be great.

I also found a crab that I can't identify, it is translucent white less than an inch long.

Thanks

looks like apstasia. yuck. make up some kalk paste and inject them. might try pep shrimp as well. welcome to the world of marine pests.

Agree that its more than likely to be aiptasia. As far as the crab, if you can catch and isolate him, do it, and watch his behavior. If you can't without ripping the tank apart, then hold off and just keep a close eye on him. Many "commensal" crabs that Hitchike on corals are actually beneficial, or present no danger- they do no harm or good. Its if they get large and start trying top get your fish that becomes a p[roblem.

Thanks for your help, since all the pics I have seen of an apstasia gave them a brownish tint, I was hoping that these were not them I have some peppermint shrimp coming in tomorrow so hopefully that will take care of them.
