ok im not an expert but i only got my leo today and from what i know from my own research here goes.
they can eat pinkies but only rarely as a treat and only as adults. they are supposed to be good for breeding femails for fattening them up
no a smaller gecko cannot live with a larger one the larger one will bully the smaller one and the smaller one wil get stressed and not eat,
im not sure on how often a smallre one will shed i think its baout every week to every other week
the sheddings for adults and babies are hte same i think
geckos eat untill tehy are full they do not mormaly over eat. i think if htey do they wil be sick. ive heard of babies doing this but they normaly learn
and crickets in the tank can nibbel and harm he gecko they will also stress the geckos.
i think thats right i dont have much experiance but ive read alot andi beleive that is right perhaps sumone with more experiance can tell me if im right.
