my gecko who i have had for over a year now has recently gone of her food even silkworms arent tempting her and she loves them. i've given her and the viv a thorough check, all the temps are fine, urates fine and her sheding is great as always, but when looking in her mouth her tongue is quite red, the rest of her mouth looks fine no sores or discharge like you would get with mouth rot, just a red tongue which i think must be sore and this is why shes not eating, can anyone shed any light please.....
