I to thought about a mini cycle but I have tested my water multiple times with 2 different kits all parameters are fine.
As far as other fish I don't think that they had caused it stress. I only have 2 osc. clowns, 2 green chromis, YWG, and a brown banded goby(that I wish was not in the tank).
This fish was very entertaining she always wanted attention. If I was looking at a coral it would swim up in front of it so that I could see her. She "ruined" a lot of pictures by putting a gray blur through them.
I was feding mysis, prime reef, formula one and two,, with nori a few times a week. All of which she was eating.
I hope the new pistol shrimp can fill some of the void left behind.
Thanks everyone for the support, and if anyone has any further thoughts please share them.
Mike
