I have a 110gal with about 160lbs live rock, 2" live sand bed, with couple snails, 15 or so blue legged crabs, 3 clowns, 2 pep shrimps, a spotted hawkfish, and the porcupine puffer. Tanks has been running for about 6 months. Water parameters are all normal except for one cant remember what it was if it is important i can recheck and give them. But the question is 1 week ago i bout the puffer, hawk, few more crabs, the 2 shrimp and 2 of the clowns. All of them eat except the puffer i have flake's, dried blood worms, dried shrimp, frozen shrimp, and dried krill he hasnt ate anything. Does it take them a long time to adapt or something wrong? Other thing about 2 days after i got him he got sucked into the power head got him out and his 1 eye turned white and lips where red but that has gone away for the most part. Even still up to the time he got sucked in he still hadent ate a thing. And id say he is about 3" long.
