They are fine with cleaners.

Mine disappeared. I suspect he is under something....

Mine is dead in less than 24hrs.

Added a tiny one to my 10G contest tank 2 nights ago. Acclimated properly (drip method for 1hr+) added him and a tiny clown, and Rose Bulb Anem.. He starting hunting as soon as I added him, and even added prep'd food. I left for the night, got home last night, and couldn't see him swimming.. so I started looking around and found him in the grasp of my Pom Pom Crab. So I'm not sure at all what happened to him. I am pondering the idea that he may have gotten tagged by the Nem. But its really a mystery right now.
