New tang, odd behavior?

[Mikeb213]

I got a yellow tang 2 weeks ago, Saturday. He was healthy, good color, and died in 2 days. The store gave me credit and I decided to try again, this guy did better though acclimation and is eating, but he's hiding alot and has started squeezing himself into corners, most concerning is the top corner, this pic was last night, and I assumed his behavior I would find him dead this morning. To my surprise when I came down to the tank he was swimming fine, bright yellow, ate flakes and picked at his sea veggies on a clip. His coloration in this pic is a little off since it was after lights out with a flash.

Edit: water parameters are good, 0,0,and between 0-5 and other livestock include 2 small clowns, watchman goby, diamond goby, cleaner shrimp, pistol shrimp, tiny crab, and assorted snails.

are you getting them from the same lfs?

Yah they both came from the same store, they have a good reputation for fish, medicated qt, copper in tanks, handful of tanks run on smaller individual sumps instead of everything sharing the same water
