So today my wife tells me that I should stop feeding my frogs so much because they're getting fat! I told her that they were just "big boned" but she wasn't buying it.

I realized after her comment insulting my babies, that I really don't know what is considered a healthy frog. So I thought I would ask y'alls opinions on the matter.

The PCF's turned to froglets mid-late June, so about two months old. Both are female as far as I can tell, and are growing quickly.
they get fed daily fruit fly, and just got big enough for small crickets once or twice per week. Both are VERY energetic hunters and seem to always be hungry. They do seem to have some belly to them, but also look slim at times. Unfortunately I can't post pics so this will have to do.

Any thoughts on the subject?

Is there any "warning signs" of a sick or unhealthy frog?

Thanks for the help!
