Hi, (sorry I posted in the wrong section earlie--reposting here)

I have about 10 serpae tetras in a 55 gallon, with some other community fish. Two of them have black spots all over their bodies. I have no clue what this is. The others are fine. But these two have lots of black spots, and are not as red as the others.

does anyone know what this could be?

I will try to post pics soon.

I'd still stay velvet.

Any other symptoms?

ok i tried to take pics, but couldnt get them clear enough so you can actually see the spots.

Zephyr, the fish seem to behave as usual. When I look really close it looks like they have a fuzzy coat on. I looked up velvet, they dont seem to have any of the behaviors.

i think i might take them to a pet shop to check it out maybe?

Try upping the tank's salt level a tad, and use a general cure.

when i add salt my tank usually gets really brown from the algae and i have to clean it good. and its only a 20 gal...a 55 gal will require more cleaning. but as you know watever the sacrifice may be for the good of all the fish ;) goo dluck with your fish hope they get better.

That's not velvet. Velvet is characterized by gold dusts.

It sounds more like this one quoted but could possibly be from other various illnesses.



A) Ichthyophonus hoferi; large 10-250 micron spores which may germinate to form large hyphae.

B) This fungus infects all species of fish.

C) Clinically the fish are emaciated with small round occasionally ulcerated black granulomas in the skin. Scoliosis is occasionally observed. Internally numerous granulomas are observed in many visceral organs. Microscopically the lesion consists of granulomas with encysted large PAS-positive spores. Occasionally large irregular shaped hyphae are observed.

D) Transmission is unknown.
