I recently got a powder blue tang but it just died 2 days later. The first picture is 24 hours in, prior was mostly in/around rocks hiding and this picture was night before he went where wasn't moving a lot. First fish in tank but bunch of corals that have been around for months. Tang was drip accliminated, didn't eat at all. Seems like shock? Nothing else is in there except some clean up crew, some serpent stars? Tank params - 55 gal, ammonia is .03, Alk is 7.0, nitrates are just under 10, pH 8.2, temp 81F
