Thanks for your imput C&G,
I was thinking the same thing, some sort of injury... He is eating fine and behaving normal...but he is constantly fighting with the lawnmower blenny; however he is usually the bully.... I will keep my eye on him tomorrow...

I found out that fish too big for my tank are more prone to disease, and infections, he maybe too big for your 55 , thats just my opinion.

My mimic tang had something like that when I first put him in the tank a couple of months back. I fed Spectrum with garlic and even added garlic to the tank with feedings. Don't know if the garlic worked, but he got better. His went all the way through (I could see through right under his dorsal fin) and was in about the same spot. At one point it had kind of white fuzzy stuff hanging off of it...it really freaked me out.

I don't know what it is, but it's a really nice rabbitfish. I love seeing rabbit fish that aren't foxfaces, because they're not seen nearly as often as you see foxfaces.

The white spot is goneââ"šÂ¬Ã‚¦ so I am guessing it was a sting or a stress spotââ"šÂ¬Ã‚¦
