I recently bought a medium rock full of encrusting lemon xenia...or so it was named at the LFS. It looks like pompom but without the stalk and like the name says it just grows horizontally without pulsing. Now after acclimating the xenia for a bit i pulled it out of the bucket and noticed a small white crab with 1 big claw and 1 small claw with a brown pattern on its back??? Any idea what this guy could be? I put him in the tank anyway thinking he was fine but later thought about it a bit more and went to look for him but he was gone. Today i found that he has molted. I cant really take a picture of him since i havent been able to see him since i put him in the tank. Plus i dont know how to add a picture on this place hahah. Any advice would be helpful.
