I cannot find my orange shoulder tang anywhere! He's been in the tank about 4 days and I haven't seen him all day today. Usually he's swimming all over the place. I already checked behind the tank and he didn't jump. I've looked around in the live rock and he is nowhere to be found. He's about 3 inches. There is a small anemone in the tank that is about 6 inches when spread out. It's closed up right now and I'm afraid it ate him... Tank is 55 gallon. I know tank is too small for full-grown size, have a 125 getting set up in the spring. LFS has a 3 year old OS tang on display that is only about 9 inches so they said he'd do good in the 55 for a few months. Been eating mysis and nori great. Tank mates are 2 clowns, a bangaii cardinal and a tiger watchman goby. Water parameters are all right where they should be. Am I going to need to tear down the live rock in case he died in there? Or should I wait a few more days to see if he shows?
