Does your gecko have her normal appetite?
No, if she is even eating at all. She has lost considerable weight and her tail is now very thin. She is awake and aware. She looks at me but her one eye on the swollen side will not open all the way. The swollen area is about the size of a large olive (half coming out of her head, with the skin discolored just in the same place). The swollen area has been there for at least 4 weeks, and had grown slightly since first noticed.
Is there any saliva coming form her mouth?
No, I don't see any wetness or drool.
Do you give her any supplements?
I have two geckos in the same tank. Male and female. I only give them a calcium dust on their crickets when feeding weekly. I also feed them meal worms/wax worms daily when crickets have been devoured. The male appears very healthy, large, well fed, and active.
The two have always gotten along, were together and the same age as juveniles when I purchased them at a pet store over a year and half ago, and I have never witnessed disputes or fighting between the two. The female laid a few eggs last year but only the one time.
