Regal Tang Infection

[travelerjp98]

As Joe mentioned, both of the clownfish on the bottom seem to have really bad cases of Ich. I hope that it's just poor pic quality.
Sometimes it saddens me when I give advice, people get defensive, and then come back later crying that their grouper ate their goby.

I think it is ich. Certain telltale signs, such as the eroded cloudy looking fins.

The pics is poor quality only having problems on this tang, water all fully tested and is 100% correct now. I was away for 15 days and had someone to feed them. They were well overfed and the nitrate level was up around 100mg/L it is back down under control now and glad I haven't lost anymore apart from a small hard coral.

You didn't say if your tang has the type of spots that I give an example of in the picture above.

They were present in the first day or so all that has been left is this on it's side.

Well, unfortunately, once one fish that has ich is in contact with other fish in a fish tank, then all the fish exposed.
The best treatment is hyposalinity. Are you familiar with this?
