Really I dont know much about pygmies, but I would also like to say that there are probably more eggs/babies in there. I would search the cage a lot to see if there is. Also he/she is very cute:) And yeah I would go ahead and put a banana in the cage to atract fruit flies, it cant hurt to try
Yeah, never put any 2 male lizards in the same cage, they will constantly fight and the tougher one may end up killing the littler one. Not to be rude but you need to really do some research before you buy a cham if you dont know this already
