I did read the diseases sticky, but this doesnt fit everything under velvet, though there are some things in common, so I thought i'd post.
I just noticed a gold SHEEN (not specks or dust) all over my new betta Firecracker. I just got him last Wednesday and it seemed like he already had this. I dont know if that is just his iridescence or velvet. Also, there is his patch on the top of his head, and it is orange and SHINY.. it extends to the top of his eyes as well.
He took some time to adjust to the tank, but now he is active and swimming, not hiding, eating (thank god) and fins are not clamped.
One thing though is he really likes to put himself in/near the corners of my 2.5 gallon tank, around the heater cord that is suctioned to the wall, and in between the filter and the wall. I dont know why. I dont necessarily see him RUBBING though, and there is no scale loss anywhere except that patch on his head which is what he came with.
