I've had a spotted mandarin in my 60 cube for a few months now, and he's been doing great. Explores every inch of my tank, hunting for pods (I literally just added new ones earlier tonight) all day long. For whatever reason, he sleeps out in the open on the sand bed. This has seemingly been fine until tonight after lights out. I was walking by my tank and saw my lone pom pom crab dragging the mandarin into a crevice in the rocks. I quickly got a long coral feeder and blasted the crab with some water and after a few he let the mandarin go. He eventually swam off, but it wasn't the most adept swimming I've seen. Not sure if he was just stunned or actually injured. Been trying to find him for the past 15 minutes unsuccessfully, so hopefully he's holed up in a cave. What should I do assuming I can catch him? I have an isolation box and also the IOAOI nano tank which is set up and running, but I don't think it would be big enough for him long term.
