I have been through a lot of shedding with Lindy so I don't think that is what this is. It started with just his lips in the front looking a little off. I put neosporin on them thinking if he'd done something to them that it'd help. Now it's spread to his nose sorta. When he sheds it goes more white and never looks like this.
Do you think it's mouth rot or something? He hasn't lost any weight, still eats his greens, not his protein as much unless I give him roaches and then they are gone. His temps are good and he has the Reptisun 10.0 tube bulb. He doesn't get close enough to get burned. Poops are good. It doesn't look like it's bothering him, just mommy.
HI. I cant tell you for sure, but sometimes Fosters lips turn white before they shed, and sometimes they turn pink, and it looks like he has on lipstick. So it is possible it is a shed. I cant really tell from the pic. Maybe someone else can.
Looks like normal colouring to me... I wouldn't worry about it and I wouldn't suspect anything unless she was showing signs of illness (Black bearding, lethargic, anerexic ect)
