Bombina Bob,
Thank you SO much for the response! Looks like my gut instincts on the lid type and the light were both right! I know to be very careful and take all advice from Petco employees with a grain of salt but the guy was correct on a lot of other things though so I considered it. That is why I added an account here, to get advice from experienced frog owners and lovers. I am going to take my friend's tank because it is taller, and just use my current screen lid for it since they have the same base size. It should fit. That way my frog has a bigger and taller home, AND a screen lid.

It might be easier to buy crickets but my lil girl eats more than I thought she would and if she continues at this rate I won't be able to afford it as a broke college student. LOL. Plus, I want to keep her healthy. I don't like the idea of frosting my crickets with calcium or whatever. IF she continues to eat what she would have in the wild, maybe I won't have to do that? Besides, it makes me feel like a kid again to collect bugs in my backyard. LOL.

Again, thanks for all the advice!
