65 Gallon Tank Can't get rid of illness

[Atk3and2]

I have been trying to get rid of whatever is causing white spots on my fish. I have an angelfish with a white spot on the lip and where the fin connects to the body. I have a rainbow with a white spot at the fin base and two along the body. Now I have a glow tetra with a red streak on the side. I have grated the tank with API General Cure, Super Ich Cure, and ParaGuard three times. These patches are still on the fish. What else can I do??

I think the Angel might be suffering from a virus, Lymphocystis.
It's common to see lesions at the base of the pectoral, dorsal and tail fins.
There is no known cure for Lymphocystis. It's usually not fatal.
The Angel's immune system might eventually suppress the virus.
Unfortunately it is contagious and might spread to tankmates with a weakened immune system.

Ugh. So I let it run its course? Or will it always be in the tank now?

Is this something a UV sterilizer would kill?

A good UVC device kills viri & bacteria & protozoans as well. So they can be a good defence against these things but they can only affect what is in the water, not what’s inside a fish.

Once a fish has lymphocystis it’s too late for UVC - every fish in the tank will already have been exposed.

It has to be UVC and not UVB, as UVB doesn’t reliably kill much except for greenwater.

Any protection to reinfection, or is that not a problem?

In the case of lymphocystis & some other viri like herpes, the virus never leaves the body so reinfection isn’t a concern.

I don’t know enough about other viri to say.

Thanks.
