Is my leopard gecko okay? I just saw this light red residue in her tank just now and I'm worried. She doesn't have any injuries either. I got her from some kid. She's incredibly stunted, shes about 4 years old and thin, was fed on crickets every 3 days but I just switched her to mealworms yesterday. He told me he hasn't fed her since Friday so I fed her yesterday and she's been doing fine. There was also a mealworm where the residue is too.
Your gecko might have had blood as a consecuence of a possible intestinal infection by worms or as a change about the food.
If your gecko loses weight or you look more blood,then,you should take it to the vet.
