Fire fish disease?

[Jaxs]

Hi everyone recently my fire fish has grown this weird flaky white stuff hanging off his tail fin. It's hard to see in the picture because he moves so quick but I can't figure out what it is.

I would say it's ich but he doesn't have any white spots on his body. Could it be hlle?

Could just be Lymphocystis (see below).

Lymphocystis:

Symptoms - Lymphocystis appears as a white or beige colored cauliflower-like growth that usually starts on the fins and spines and sometimes spreads to the body. Initially it may be small (looks like ich), and then grows in size (which is how you know it’s not ich). Lympho is a virus that many fish carry for life. Fortunately, it is rarely fatal or even harmful to the fish, and symptoms will come and go.

Treatment options - No known cure or treatment exists. However, feeding vitamin-enriched foods and maintaining pristine water conditions may expedite the “going away” process.

Ok that makes me feel a lot better. He's the only fish I've added to my tank so far so I'll give it some extra time before adding anything else to see how it developes. Hopefully it's just what you mentioned. Thank you!!
