I had two LFSs trying to get 3 of them for me— after about 4 weeks one located 2 of them. I picked them up a day after they hit the store, and placed them into quarantine with no other fish. They both looked very healthy and active. One slowed and then stopped eating after a couple of days; I checked for flukes and saw none— but began General Cure. Long story short, despite some heroic life-saving efforts on my part, the one who would not eat died.
On the plus (+) side, the one that remained healthy is now doing well in a tank with some big boys— an Emperor Angel, Purple Tang, Harlequin Tusk, Lunar Wrasse, etc., and charges at food right in among them. One thing I didn’t know is that the Pyramid eats from the surface of the water as well (such as floating pellets). Overall, a great, great fish, and worth the wait.
