Please Help My Gecko Is Not Eating!!!!!!!!!!!

please help my leopard gecko is not eating I have two 4 inch juvineiles one is health and fat but the other is very skinny and you can see his/her bones under the skin i feed them enough mealworms every day and crickets every week and provide proper lighting and heating

well do you stay there and see if this fat one is hogging the food? maby if you separate them, sthe small one will gain weight, or hand feed. unless it is just strait up not eating anything. you may have to see a vet, but im not sure.

Hi Joe-first off- they really need to be in separate cages/tanks especially since there is one that appears to be either alot healthier than the other and/or very dominant
You need to provide some more info on the tank/temps etc for anyone to try and help but my advice is to get them into see a vet or at the very least -get a fecal sample from them into the vet asap
They very well may have parasites-worms of some kind and possibly the skinnier one may have increased coccidia levels from being stressed out in a tank with a very dominant cage mate

I see that you mentioned lights-Leos really do not need any overhead lighting on their tanks/cages

They do quite well with just ambient room lighting and if the room that they are in is very dark-leave a light on during the day
Very bright white light such as the basking bulbs used for diurnal lizards will stress them out

Are you using an under the tank heater (UTH) as your heat source-this is a necessity for bely heat for them to properly digest their food and the temps that matter are measured on the floor of the cage/tank-not the air temps

I am sure that this eventually will be moved to the Leo forum where it will get more replies?
Good luck with them and be sure to get them separated and into see a vet asap
