Give it some extra protein to boost the immune system and its digestive system so he/she has the energy to pass the parasites. This can be done by giving it a pinky when he opens its mouth 1x per week. Then feed insects the rest of the time. You also want to rehydrate the poor guy. It looks extremely dehydrated, mist 2x per day and keep it really hot in there. This will really help, you can also give it some electrolytes by diluting some gatorade or pedialyte 10/90 liquid to water ratio.
