unknown disease

[Iago Silvestre]

Good evening, I need help again. During the treatment for ichthyo due to hyposalinity, a new disease emerged, I don't know what it is. I'll post a picture so you can guide me better.

Are you seeing any other symptoms like rapid breathing or the fish not eating?

The yellow tang has some mild head and lateral line erosion, not much you can do about that, but it won’t harm the fish. Avoid using dusty carbon in the tank.

The sailfin tang has something else - those spots look like mucus plugs that develop due to some stress. Hyposalinity commonly causes that, but it generally goes away after a few weeks.

Guys, I'm still having problems with my fish and I can't identify. Here are some updated photos, I need help with identification.

What is the salinity at? How did you measure?

I see raised bumps which suggest mucus cones often associated with skin irritations but these appear to be based on size marine ich which I hate to saty but will require quarantine and likely treatment using either
Coppersafe or Copper Power at therapeutic level 2.25-2.5 For a FULL 30 days (do not interrupt this 30 day period) monitored by a reliable Copper Test kit such as Hanna Brand- No API brand. Also monitor Ammonia levels while in quarantine with a reliable test kit and add aeration during treatment using an air stone.
The display tank will likely have to be kept fishless (FALLOW) for 6-8 weeks to assure the existing parasites go through their life cycle without a host fish and die off

Qual é a salinidade? Como você mediu?

Estou subindo aos poucos, atualmente está em 1020. Eu medi com um refratômetro

I'm rising little by little, it's currently at 1020. I measured it with a refractometer

Are they not parasites?

This is a good example where gross visual symptoms are just not sufficient for an accurate diagnosis. A skin scrape of a fish, under a microscope is really needed. I understand that you likely are not able to do that. Can any pet stores in your area do that?

What level of hyposalinity did you reach and for how long?

I kept it at 1009 for +30 days.

I had a friend that this happened to his regal and convict tang during hypo as well. He started to bring salinity back up, the regal recovered completely but the convict ended up being too far gone.

I think then, you can rule out ich, crustacean or worm parasites.

That leaves some sort of bacterial issue as the next most likely cause.

I would consider treating their water with a broad spectrum, gram negative antibiotic like Neoplex or Kanamycin.

On Tuesday I'll have access to a microscope and I'll show you the images/video here to help me with the identification.

O.K., just be gentle yet firm with the scrape. I use a dull knife and drag it over the fish's skin in the suspect area, just enough to collect some mucus. I then put that on a microscope slide and look at it at 40 to 80 power. Look for anything moving.....

Acho que então você pode descartar parasitas ich, crustáceos ou vermes.

Isso deixa algum tipo de problema bacteriano como a próxima causa mais provável.

Eu consideraria tratar a água com um antibiótico gram-negativo de amplo espectro, como Neoplex ou Kanamicina.

good night friends. I did the scraping and observation with a microscope and nothing was found, I have no experience with that. Could it be some bacterial infection? What human remedies can I use and what dosage? I'm thinking of using antibiotic to rule out the possibility of bacterial infection.

The spots are still the same? Have they gotten no worse or no better? It has been six weeks. Diseases usually get better or get worse over time, not stay the same. After you had ruled out most other issues, I had thought bacterial disease, and suggested Kanamycin or Neomycin. However, even bacterial disease would have changed in this time I think....

It seems to get worse, the fish is now mostly covered in spots. What dosage to use?

Follow the label instructions. Neoplex is one scoop per 2 gallons, one dose for 7 days. Always dose antibiotics in a treatment tank, not your main dispkay.
