Yellow Watchman Bacterial Infection?

[jackalexander]

So i’ve had this goby for about 4 months and probably a month ago, he began to develop a white scrape. I had assumed it was just a scrape because i saw it shortly after I had been moving my rocks around to catch a six line. A month later and it seems to be healing but still a reddish sore. Assuming it’s a bacterial infection but I don’t have a QT right now. Any ideas what I could do?

That looks like a severe bacterial infection, down to the muscle tissue. You would need to move it to a treatment tank and dose it with a good broad spectrum, gram negation antibiotic such as kanamycin. With that much skin damage, the fish will have difficulty with maintaining a proper osmotic balance with the water. You should keep the specific gravity of the treatment tank a bit lower, say 1.020
