I've been a little worried about my HM Rusty G. He was in a 20 gallon tank but due to the divider my other HM got over to he's side and didn't so much fight but he harassed him. So I had to move Rusty G. Into a small tank. ... Well I take a lot of pictures of my fish for my friends to see. Well I took a picture of him a few days ago and saw he's tail fins ( I'm new to owning beta fishes so forgive me if i sound stupid
) there are starting to turn gold. here a pix
I thought it was Velvet but some of the sign of it he doesn't show, just the gold fins. Do you have any ideas what it could be?
