Zebrasoma xanthurum white spots

[vollkomm]

Hey Guys!

The day before yesterday I brought home this purple tang with a salarias fasciatus. They are both currently in an observation quarantine tank. The next morning, small white dots appeared around the eyes, on the front fins and on the left side of the tang, but nothing visible on the salarias.

Both fish are eating normally and are active, but the tang has a clicky movement. Please help me identify the white dots on the tang, are they ich, mucus or something else?

If ich CP treatment can be suitable for them?
If you need any further information, please let me know!

Thank you,
Joe

Since you just acquired these fish and have them in a QT, I suggest you follow the standard QT protocol. Assuming you can get CopperPower or CopperSafe preferably, or Cupramine. While the tang may or may not have ich, QT with theraputic treatment is the recommended approach. Please see the referenced link below.

Welcome to Reef2Reef!

Yes, that may be the start of marine ich, Cryptocaryon irritans. In the US, the best treatment is either hyposalinity or Coppersafe. I've used chloroquine, but we cannot get that drug very easily now.

I like to use hyposalinity because it also takes care of flukes, which both of these species are known to get. Here is a post about that:

Hyposalinity

Hyposalinity Jay Hemdal 2021 This term refers to a long-term bath treatment for marine fishes in which the salt content of the water is lowered and held below the point that certain parasites can survive. The salt level reached, and the time of the treatment are the two variables...

Finally, getting salarias blennies through quarantine can be difficult - they like to graze on algae, and your tank won't have any algae in it. You can try Nori, or perhaps some frozen foods with algae in it.

In your country, you should have Aquasonic Oodinex and even coppersafe. Yesterday you said flukes- be careful treating for correct symptom rather than guesses.

I prepared for the arrival of the herbivores, so there is a lot of algae in the quarantine tank at the moment.

Because of the hyposalinity, do you think it would be advisable to first clean the aquarium of the algae, because I think they would die and start to decompose unnecessarily in the water, or would copper be a more optimal solution in this case? If hyposalinity is the solution, is it appropriate to control the ammonia with zeolite?

By the way, I can solve pharmaceutical grade CP.

Regardless of the above, which solution do you think puts the least burden on the fish and which provides the most comprehensive protection (hyposalinity, copper, CP or something else)?

Thank you very much,
Joe

CP will actually kill all of the algae at once, causing an even greater issue than hyposalinity does.

If you want to preserve most of the algae, Coppersafe or Copper Power would be the best choice if you can acquire that quickly enough.

Otherwise, hyposalinity at 1.009 specific gravity would be my choice, watching the ammonia level and offset any ammonia build up. Hypo has the added benefit of controlling flukes. I don't see evidence of flukes, yet, but all new fish should be treated for them.

Did you ever figure this out? I see them on the fins too.

I follow the general qt protocol. At the moment I would say the spots may have been lympho rather than ich, the fish are fine at the moment thankfully.
