Ok maybe i should relate what has happened so far...
These geckos(2) came shipped from a breeder together. They have a 100x50x36 enclosure, papel towel substrate, 2 shelters (hot side cold side), infrared lamp 75 wts. One of them( Malk) started to hunt down the crickets and was in very few occasions succesful in catching one, the other(Anep) would simply not try and catch one. When their tail was shrinking, i suspected parasites and took them to the vet a week ago. The vet confirmed me my worries and they did have parasites. He administered a medic into both of them, and told me to come back next week for the same treatment, and meanwhile force feed them if they have trouble, specially the one not eating...
Malk would occasionally just lick the head-torned crik and eat it without making a fuss, but Anep would just deny any offer (criks, mealworm, etc) and its with Anep im having trouble, since im the only one in the house who has "guts" to hold a dead crik..."sigh"
So its not really to put any medics in him, just to feed him so he gets a bit more active...
Thanks again
