Congratulations on getting one from Reef cleaner that actually had them. I've ordered three and never had one, with a nem friend.Ever since I got into the hobby I have wanted Pom Pom crab. Thanks to @F i s h y, I was able to hitchhike a couple in on his shipping with reef cleaners. These guys are TINY! I suspect when they go in the tank I may never see them again. The second pictured crab is missing one of his Pom poms. I’ve heard sometimes they will frag coral to replace a lot pom Pom. As long as it isn’t some of the GSP, we can stay friends lol.
I still see mine all the time. They aren't all that shy.
None of them have ever picked up anything else in an attempt to replace the lost anenome
