Hi All.
I have a couple of Sliders one of which is a Female RES baby which i had for about two weeks now. I noticed about a week back it got a black spot on it's nose and now after a week it's spread to between it's eyes as well. At first i thought it was a burn mark but the Heat and UVB Lamp is far up and impossible to touch. It's not grease or color of any kind. It swims in the water normal and eats now and then as well. The heat level is very mild and not burning at all. I've searched the net and this forum for some similar circumstances but none found. Attaching pics. Any guesses?
