problem with fish, and I don't know what it can possibly be!!

Good day,

I'm having an issue with some of my fish and I don't know whats happening. I started to notice some reddish blemishes on the fish, which appear to be eating the fish flesh. I started to see another fish with a minor blemish compared to the photos, and it seems to be starting from the head. The water parameters seem to be in place, and the coliform and enterococcus readings don't indicate a vast bacteria load. What can this possibly be? Any help would be appreciated.

I read that it is recommended to use Kanaplex, Metroplex, and Furan-2. (the trifecta) .

Hard to tell, but possibly Uronema.

Do you have any pictures of the other afflicted fish? Things can look differently post-mortem.

Have you had any significant changes in salinity, temperature, etc? Have you checked parameters, ammonia particularly?

Red lesions can indicate a few diseases, like bacterial infections or uronema marinum. Any recent additions (not quarantined)? Fish, coral, cuc, etc?

Yes, that looked like a bacterial infection of some sort.

You won't have high levels of coliform in SW. It doesn't live long and it only effects warm blooded animals as well.

The most common bacterium you will find in Saltwater are vibrio, mycobacterium, and pseudomonas which are gram negative.

Posting pictures of your current fish non post-mortem will help us all to help you.
