What a shame that the petstore didn't even know what species they were selling. I don't think they have any right to pawn animals when they don't have any knowledge about them at all. Unlikely that the eggs are any good since they're probably not fertile. Sorry for your loss. If you are interested in getting another one you will probably need to make some changes to your setup (especially if you get another female) since the petsore probably gave you other bad advice as well, as they are notorius for doing. Please ask questions and take a look around here on the forums to make sure you have everything set up correctly first.
