Melanurus wrasse scaly whitening

[vollkomm]

Hey Guys,

I brought home a melanurus wrasse on day 2024.04.08., it is currently in quarantine.

After we got home, I noticed a small dark bump on her right side, which today has become the center of a one-centimeter-diameter circular scaly whitening.

By morning, the fish's appetite has decreased and it is less active, but it is still swimming and interested. There is also a Valenciennea Strigata in the quarantine with her, who behaves completely normally as before and does not show any similar phenomena.

Please help me identify the problem and what would be the most optimal treatment.

That could be Uronema. If so, I'm sorry, but there is no good treatment for an advanced case like this. Here is an article I wrote about it:

If not, what else can I possibly treat? Bacterial infection perhaps? Valenciennea strigata, which I quarantine with melanurus, does not yet show any symptoms of the disease. What can I do to protect him? I can solve to separate them.

Uronema is not usually 'contagious' - it can be in many tanks with no symptoms. The key is good water quality. It could also (as you said) be an infected injury - and you could try a broad-spectrum antibiotic in a QT tank (such as kanamycin) - I don't know what you have available. Agree, though that my first thought was uronema as @Jay Hemdal suggested

Uronema only infects certain species, I’ve never seen it in a goby. Most often affected are wrasse, chromis and anthias.

Thank you Jay! You were right, the fish sadly passed away. The goby looks fine.
