Oh, I personally would not feed them too often because they are very fatty. It's kinda like the Mc Donalds for frogs. "Super size my frog" Would be an excellent movie.

On that note though, I'm not one to talk, my baby is looking a little "hefty." It's gotten many treats. You should be fine just using them "sparingly." You will notice if your frog is getting obese or not. It's kinda hard to say what certain schedule you should use them as or an exact number/how often to feed, because it depends on what you have to offer, and how your frog's overall appearance looks weight wise. So in conclusion, basically I typed up a bunch of stuff that didn't offer any real answers, lol.
