Disease ID Needed

[Browndawg80]

I have a sick fairy wrasse, see photo attached. I had a QT set up with several fish in it (purple tang, two fairy wrasse, two clownfish, two firefish, a coral beauty and a chromis). The last fish added was the purple tang, which showed some signs of ich. I treated the whole tank with Prazi Pro for three days before starting TTM. After the first transfer, I did not see any additional signs of ich. However, during the third transfer I noticed some white blotches on this sick wrasse, but not on any of the other fish. I'm thinking that it may be brook or velvet because it looked different from the ich spots on the tang, so I decided to do a four minute freshwater dip. The attached photo shows the fish as it's in the FW.

Can anyone identify or advise on next steps? Thanks in advance!

Forgot to mention that this fish was healthy and eating in the QT for 2 weeks or so before I started with the prazi and TTM, I also had my LFS hold him for 2 weeks before I brought him home so not sure if that would eliminate anything. He is still alive even though he looks terrible in the picture.

If only one fish shows symptoms, and especially clownfish of all seem healthy, my first guess wouldn't be brook or velvet. Any of those diseases would have spread fast to every fish.

Whitish patches can be a lot, from bacterial to uronema.

Bacterial might be the most likely, given that it is the third transfer and there have been likely some scrapings while catching the fish.

Are there any other symptoms beside the whitish areas?

Also, should it be brook, velvet or uronema you need to treat all fish and not just one or you will transfer the infection to your DT.
This is especially important with uronema as it is opportunistic and can't be eliminated from a system with going fallow.

... I also had my LFS hold him for 2 weeks before I brought him home so not sure if that would eliminate anything. ...

It doesn't eliminate anything, but adds a lot more pathogens the fish may have been exposed to and infected with.
I made the mistake with my percula pair. Luckily I was there when they were dripping in a new batch of freshly imported fish (no quarantine of course) and got them out before the sh** (=brook, velvet and what else) hit the fan. So the clowns only brought some nice ich home which gave me opportunity to practice hyposalinity treatment. :angryfire:

How should I proceed then assuming it's bacterial?

 

[ThRoewer]

If it is bacterial you can try an antibiotic, preferably broadband.
Methylene blue has anti bacterial properties too and can be used in 20 to 30 minute dips.

If the fish is otherwise doing OK it may get over it by itself.
Is it getting worse?

I made the 4th transfer this morning before work and dosed the tank with a product called kordon rid ick plus which contains formaldehyde and formalin in addition to malachite green.not sure why I dosed it, I guess because I had it on hand and felt the need to do something before I lost the fish. Fish disease are so hard to diagnose. Anyhow much to my surprise the fish is looking much better tonight and is actively eating. Fingers crossed that he continues to improve and that no other fish start showing symptoms.

Rid-Ich Plus is the right to treat brook, uronema or trichodina.
