Missing Pepermint shrimp.

I don't know about that, I have one in my 16, didn't see him till just the other day and he has been in there for 3 months. Kinda like my star fish, Know he is in there because once in a while I see an arm reach out and grab a crab pellet a mysis shrimp that get close to his lair. Other than that I haven't seen all of him since the day I put him in the tank 6 months ago!

 

^ was that a sand-sifting starfish?
Sorry about the shrimp dude. my anemone has only eaten dried krill so far...but did sting/surprise one of the Tonga snails one time. Hopefully your shrimp will show up again. Try putting out his favorite food...
