Sick baby gecko with green spot on her belly

[Sunny14]

Ok so I got 2 baby leos almost 2 weeks ago. One (Phoenix) eats just fine but the other (Pixie) will not eat, I have been feeding her a slurry since a few days after I got her. I am going to divide their tank horizontally its a 20g long with repti-carpet and 3 hides 1 cool 1 warm and one in the middle. They have a heat mat and a heat lamp (set at low heat). So the other night when I was feeding Pix (I drop the slurry on her nose with a syringe no force feeding) I noticed a green dot on her belly I'm not sure wat it is from. Could anyone tell me or give suggestions as to wat this dot could b? I'm hoping that once I separate them she will eat, both babies are skinny so I'm giving them lots of good food and vitamins to help get them to a nice weight. I'm just more concerned about Pixie because shes not eating and shes skinnier that Phoenix. Thanks

The green dot could be some feces that haven't come out yet or one of her internal organs. It's probably fine. She may not be eating because the other one is bullying her so separating them is a good first step. If she continues not to do well, she will need a vet visit to determine what the problem is.
