Need help trying to find the source of the problem.
This is in my 75 gallon reef that's been setup almost a year now with that fish, a pari of false percs, and a 6-line wrasse in it. I bought the tank used and the tang came with it. I believe he was in the previous owners setup for two years. Was doing great until yesterday when my Azoo powerhead went crazy and burnt out . He then started hiding out and staying still. I have since taken out the powerhead (I have two maxijet1200s in there still until my AM3000 comes back ).
Please give me your ideas on what might be the cause of...well, by this afternoon it will probably be death.
Does it look skinny? I had a yellow tang that suddenly stopped eating, got very skinny and died. I was told that it had died of a internal infection. Maybe you should move it to a quarantine tank in case you need to give him some medical treatment.
I recently read (I think on Tullock's natural reef) that ich is not necessarily too obvious in the early stage. So maybe you should treat as a prevention anyway.
