I have hand fed my crested gecko since day one. I know not everyone has time for that, but he is my only one so I am able to. I give him lots of different items. Rhinoplasty Crested Gecko i mix in a contact lens case and use a medicine dropper to drop the diet onto his nose. He usually stops jumping around to lick it off. I also feed him dubli roaches and crickets off tongs. He loves to eat them. I have heard that if their enclosure is to large they have a hard time finding their food. If I leave the RCD in his tank I do 3 parts water to 1 parts powder because it used to dry up over night when I was doing 2 parts water to 1 part diet.
