On Saturday, I purchased a yellow coris wrasse from a member of my local reef club. It looked healthy amd he said it had been in his tank for a few moths and was eating brine or mysis, I can't remember. So I bring it home let it acclimate for about 45 min then add it to the tank. He is the first fish i have added to my 250, I also added crabs and snails on the same day. When I first added him, he was swimming around. Later that day, it was burrows in the sand. The next morning, he was swimming around, but later that day I hadn't seen it again. Ever since Sunday mornimg, I haven't seen it and I think some of the crabs have gone missing. Should I be worried or is this normal?
