I'm not sure if velvet is really obvious or not, but I'm afraid my Epsilon may have it. I mean, he's acting completely fine - eating, swimming, responding, whatever. But I was nervous, and after I took a really good look at him with a flash light in the dark, I realized he has a very, very very thin dusting of copper along his sides, but not all throughout his body. Well, I dunno if it's copper, but it's sort of an orange-y color, quite faint.. could this be velvet?
If it is, how long would he possibly last? I don't know if I have time to go all the way to Petco to buy him the stuff he needs - I've done some research on anti-parasitic medicines, like Atabrin, Aquarisol, Quick Cure, and Aq salt. I've plugged his heater in, and the temperature is around 80 - 82 degrees, and I'm keeping the light in his tank turned off, for good measure. I'll do a 50% change of his water tomorrow (treated).
He lives in a 2 gallon tank with an under gravel filter. I got him about a week ago.
