Yellow Tang in Distress

[PacsAdmin77]

Hi All,

I’ve had my Yellow Tang (YT) for about 2 years now and it’s been relatively healthy. However, about 4 weeks ago, I’ve noticed that it was breathing pretty hard and had a steadily declining appetite. It would eat a few mysis and a few bites of the Nori. It continued wasting away (losing weight) and breathing hard to the point where I can see its bones. And this morning, I’d noticed an abrasion on its gill cover. I’ve performed weekly water changes, my water parameters (which I’ve checked weekly) are near zeroes for nitrite, nitrate, and ammonia, pH is 8.2, salinity is around 1.025, and none of my other fish are experiencing the YT’s issues. The only possible, I mean remotely possible, cause that I can think of is that I added a dual MaxSpect XF330 system to its tank around the same time that it first exhibited these symptoms and somehow, it became stressed-out by the increased water flow?But, as I’ve said, none of my other fish are affected. At this point, things are looking bleak for the YT. Can anyone think of any reason(s) why my YT is in so much distress?

lets get some good eyes on this.

That is an infection, I am not sure the cause but you should remove and treat this fish in a quarantine with antibiotics. Nitrofuracin green is best, but hard to find in a timely manner. In lieu of, metroplex, furan 2, and kanaplex for 10-14 days would likely suffice.

Antibiotics are slow to work in fish, so you'll want to move quickly to save the fish.

Well, my YT finally succumbed to whatever was affecting it. Should I be concerned about the other fish in my DT? Should I consider prophylactically medicating, or should I just observe them for now?

I'm having difficulty finding those medications in my drug reference texts. Are they proprietary names? If so what are the chemical names.
Thank you, Mark

Metroplex is made by seachem If I'm not mistaken. Hope that helps.

Thank you for your reply. I'm a veterinarian and would prefer to use pharmaceuticals rather than proprietary products. Metroplex appears to be metronidazole but so far I'm stumped by nitrofuracin green.
