Hey everyone I am really confused about what happened in my reef tank. About a week and a half ago I was preparing to leave for a vacation with my family. Two days before I fed my fish a new type of food I had received from a friend. The next morning my male Red Head Solon wrasse and my female Carpenters wrasse were hiding in my rocks. I located them both breathing normal, looked normal (slightly pale but nothing to concerning.) I was kind of nervous since I was leaving in a day but there was nothing I could do so I hoped for the best. The next morning when I woke up I found my fox face sleeping in a different spot. I didn't think any of this because he sleeps oddly. Anyway I left on Monday and returned Friday. I walk in to my room and the first thing i see is my fox face dead sucked against a power head. I was furious. I found both wrasses still breathing but slightly faster. I am pretty scared at this point especially for my other fish. 5 days later my carpenters wrasse is dead. Currently about two weeks since this started my Solon wrasse is still alive but most likely on his way out. I doubt the people caring for my tank did anything normal, all they do is feed the fish and fill the tank with water. All parameters are normal. Ammonia 0, nitrate less than 1, phosphate .02, salinity 1.024, temp 80 degrees F. What's odd is that during the time of this i never noticed any true disease looking clues on my fish. ( I never got to observe my foxface cause he died when I was gone.) My two wrasse looked a little pale but other than that looked normal and fat. However their swimming habits were odd. If they came out (happened like 4 times) they would scrape the bottom of the sand and acted almost blind. They would respond to my hands and light from my flashlight. They hid all day everyday while sick or whatever it is. All my other six fish are fine, eating, and acting normal. This is a 93 gallon mixed reef. I am really nervous and plan on picking up a new fox face this week. If anyone could share some insight or offer some help that would be appreciated. If you need to know anything about my tank please ask. Thanks again.
