Atlantic Blue Tang issue

[mthird]

My Atlantic Blue Tang is starting to look sick. He is eating ok, but has developed small brown spots all around his body. All of the fish get along and appear to be content. I was wondering if anybody knew what this was and what the appropriate treatment should be, if any.

Thanks,

Michael

Update

After doing some research, I think I've identified this is a type of flatworm. I purchased some PraziPro and set to work to catch Mr. ABT. I eventually gave up and dosed the tank directly. I know this isn't the safest thing thing to do (despite the label), I didn't want to stress all the fish too much.

If anyone is interested what Xenia's think of this, here's a pic:

This was 30 minutes after the treatment. Every stalk puckered up, which looked a bit funny. An hour later they are beginning to open again.

I took a few more pictures in case anyone is interested. I'll try to update this thread daily with any changes.

Hmm, that might be black ich, although its hard to tell from the pics. If you can catch him, put him through an aerated freshwater bath with matched temp and pH. If it is black ich, you will see if fall off if him during this process.

As for the prazi, you can mix this into the fish food directly and feed it to him instead of treating all the water in your system.

I treated my 240 with prazipro with no ill affects. I was treating skin flukes. I didn't lose anything and the product works great.

Atlantic Blue Tangs ususally end up with troubles in captivity. They should stay in the wild IMO.
