Just so you know, I have had this Gecko for two days and his condition is not my fault. I am only concerned about getting it better. Thank you to those who have offered geniune support
Aww, that's awful. As said immediate vet care is needed. Faecals are a must. There are plenty of people on here who can help, good luck with everything.
Sorry if i came across strong myself, i deal with geckos like this all the time and its horrible.
My suggest aside my CAPS will be a great help to you, just make sure the critical care is in the right measurements so you dont put the little leo's immune system into over drive
Im sure you are doing all you can, which is more than some people would hence my comment before about people who neglect and hand over to us.
Since posting I have managed to encourage him to eat two wax worms and a meal worm from a pair of tweezers. He has since appeared to be more active in his enclosure. I have found the recipe for critical care and will make up the soloution tomorrow. Aparently he has had tests for internal parasites but nothing has shown up and he is three times his original size when the previous owner got him.
