Fish stopped eating?

[maxxin69]

For some reason my Regal and Blotched Anthias stopped eating out of the blue. The Blotched recently died after eating like a pig for about 2 weeks. Now my regal, who has been eating just as much for about 1 and 1/2 months stopped eating. They both were eating Hikari Mysis soaked in garlic and either Angelixer or amino acids, along with New Era pellets. I tested out all of the usuals and nothing came out as striking (Nitrates 1ppm, ammonia 0, nitrite 0, alk 8.8, ca 400, mg 1450, ph 8.3, phosphates at .02 and salt at 35 ppm). I tried using various foods like clam, krill, and rod's food but she isn't biting. Any other ideas? I was going to try out live blackworms tomorrow and see if that will do anything.
I also do have a clown pair but I doubt they are picking on anyone since they are only about 1 inch, but they are still eating well. It is in SPS dominated tank and corals live with no problems.

Any suggestions? :sad:

Sounds like a disease. When was the last fish added to this tank?

The last one was the botched. The store I bought him at though quarantines before selling. The only fish that wasn't quarantined was the regal.

Very few LFS quarantine properly or thoroughly. Not even DD does. For example, unless your LFS treated with Prazipro - 2x, 5-7 days apart - your fish might be succumbing to gill flukes. But you'd need to perform a FW dip to confirm that - tiny white worms will fall out of the fish after 2-3 mins. Works even on a recently deceased fish.
