So about 4 days ago I noticed my Silurichthys hasseltii was breathing very heavily and stopped eating, 2 days later I notices a red lesion behind his pelvic fin, Tonight he died and the lesion looked worse, I am wondering if anyone knows what could have possibly caused this and if I need to be worried about the other fish in the tank.

Looks like septicemia with the red. Likely internal infection.

It’s maybe a internal thing and not transmitted. I’d just make sure ur fish aren’t overeating.

IDK, Ron may be right but these things are hard in my experience. Is the lesion that teal, flesh colored oval behind the pectoral (not pelvic, as you wrote?) fin? And the circular redness around the pectoral fin a later development?

It does look very full but not being familiar with these fish at all, IDK if they can die from overeating, or maybe it's a bloat, or a swelling / water retention.

If your water parameters are good and all other fish act normal, I'd not worry much, just observe more intently.

We don't know what kinds of pathogens our fish come to us after caught from the wild. It'd be logical to assume they come with much nasty stuff. External is easy to treat. Internal is very hard, laborious, and expensive.

Pelvic, sorry it was 4 am when I wrote this. I assumed it was an internal thing, but because of the red lesion I just wanted to make sure it wasn't anything concerning for my other fish
