HLLE on this Achilles Tang? or brook?

[kingkai512]

hello,
i've had this guy in .6-.7 copper for about 2 weeks, had an issue with flashing and scratching so i dosed prazipro twice at 3 days apart, now i am seeing these markings on him.
At first i assumed hlle but there are some that arent om his lateral line, so is this brook? i know it can cause some sloghing of the skin due to excess mucus secretion but achilles tangs are thin mucous fish, so is this what it would look like on an achilles?

That does not look like HLLE,

That may be an issue from cuperamine levels being high. Therapeutic level I believe iss .35-.50 and I see you were up near .70. How were you testing for copper?
I’m not saying it isn’t brook because I haven’t seen brook on Tangs that often. Are there marks on his fins also? Hard to tell in the pics

Yes one fin looks a little ragged, i know brook can cause brittle fins as well

Which kind of copper? .6-.7 is low for chelated, and a bit high for ionic.

It almost looks like secondary bacterial infection from fluke infestation to me but it could easily be brook.

Fish these days have been coming in with 3-4 of these ailments. Since you’ve done prazi I’d do metroplex (treats brook) every 48 hours for 14 days. I use it in conjunction with copper, but I’d have an air stone AND powerhead aimed up to be sure.

I agree that’s not HLLE.
