Red Splotch

[Zanotti]

This is a new clown. Was in my QT for about three days. Was eating well, then this came on in about a day. He has a saddle shaped red splotch over the top of his body. He's listless, won't eat and has his fins clamped.

Ideas?

Hard to tell from the pic, but I believe it may be Brooklynella. The treatment for this would be a formalin treatment either in the qt tank, or as a SW bath. I had a heni with this disease in qt and the formalin baths did a good job.
Here is more info.

Look around and see if this looks at all like it.
A few other questions first.
Is he still in qt?
What are the water parameter, PH, nitrate, nitrite, ammonia?
Possibility of an injury?
