Infrared or black heat lights are not detectable in leo gecko's light spectrums, thus as long as they're using a red or black bulb stress should not be a factor. As for belly heating, I've always used a red heat bulb and it warms my substrate (reptile carpet) to a pleasant 88 F on the hot side, so I don't see how a UTH could be all that much more effective.



As for your feeding problems, I'd give the little fellers a little more time to get used to their new surroundings. Geckohappy is right, separation would be a good start as the sex drive of the male could be stressing the single female. Rather than getting a whole new tank, I would suggest simply inserting a divider in the middle of your 30 g (make sure you put something non-transparent in so the gecko's are truly isolated), as 15 g per gecko should be plenty of living space. Since this will most likely require the purchase of a new heating source, it wouldn't hurt to try buying a UTH and putting it on one of the gecko's living space to see if that does in fact make a difference. If you are using a simply incandescent bulb (white light), go purchase a red or black bulb immediately - I would suggest red since it allows for convenient viewing during the evening hours. Also I would try picking up a few of the mealworms from the tray and physically placing them in front of your geckos to see if they are truly disinterested in food or simply are too lazy to go retrieve them from the dish.



Good luck,
