I have a new 75G SW tank. It has fully cycled and had three small damsels in it. I purchased what appeared to be an active and healthy yellow tang about 2 weeks ago. When I purchased him I had a great deal of brown algae (diatoms, I assume). He seemed healthy and would swim fairly actively. However, he was quite shy and would hide behind the rocks whenever we were near.
Over the two weeks, I have never seen him eat. Because he would never come out from the rocks when I was there, he never ate any of the flake that I feed to the Damsels. I would try some Nori on a clip every other day, but I don't think he ever touched it.
The brown algae is no gone and the Tang doesn't come out much. Yesterday, he was out and seemed very lethargic. He still has his color, but I fear that he is starving. He won't take the flake or the Nori. I put some regular shrimp in there the other day and he didn't take that either. He still won't touch the Nori. I did a water change (15%) today; First one after adding fish three/four weeks ago.
Any suggestions? I fear that I will lose him soon.
conditions:
Amonnia 0
Nitrite 0
Nitrate 0-5
PH 8.1
