Help identifying disease

[Mark_Tampa]

Hi all,

I have 3 blue reef chromis - currently in QT.

On one of them - a couple of days ago - I noticed had a few scales that looked slightly lighter in color.

Last night he seemed withdrawn and breathing heavily. Today he is severly discolored, and has red marks between his anal & pelvic fin, and down toward his tail. Pic attached. Seems likely I will lose him, but wondering on best course of treatment for the remaining 2. What disease does this look like to you? Is it velvet? Or some kind of bacterial infection?

FYI - water params are:

Ammonia - 0
Nitrites - 0
Nitrates - 1ppm
KH - 10
ph - 8.0
temp 79.1F
salinity 1.024

Thanks in advance!

Mark

Can't tell for sure from the pic. The red marks indicate a possible bacterial infection; although Uronema marinum is another possibility, and chromis seem to be especially susceptible to that parasite. If it was Ich (or Velvet) there should be "dust" covering the fish and/or rubbing/scratching.

I agree. Its not velvet. Uronema seems to be showing up on chromis a lot lately and if it wasn't for the frequency of chromis dying from this stuff, uronema wouldn't be my 1st guess. Tough stuff to cure. Was this fish in a QT, or has your entire tank been exposed?

Fortunately in a QT! So what would the suggestion be to treat the other 2 (unfortunately this one died shortly after I posted)? I do have some metronidazole & copper in reserve. The other 2 are showing no symptoms so far.
