I never heard of Velvet until a few minutes ago. I noticed that my mollies have yellow or gold spots near their middle sections. The spots look about the same size as the black or white spots already on them, but I never noticed them before (doesn't mean they weren't always like that, I only just got them Saturday).
They don't appear unhealthy and I haven't seen them scratching against anything. They also eat algae wafers like they're going out of style! I don't think they are acting sick at all.
None of my other fish have this, and all are active.
My ammonia and nitrite are 0 and my nitrate is around 30 ppm
(working on getting that down, the tap water I started the tank with is over 140) Temperature is 76 degrees.
I tried shining a flashlight on them with the lights off and I could see it shine but again, I don't know if it's been like that. Could that be part of the fish's color?
