Feeder fish are worthless and Petsmart/Petco sell the same worms as Walmart except at a huge markup..
My frogs mostly eat nightcrawlers sold at Walmart, 18 large worms for $3.25, buy these. They've been on this diet for years with no signs of illness. I supplement their diet with reptomin, tilapia filet chunks, frozen foods such as large mysis shrimp, and crickets as treats. This diet is much healthier and cost effective than feeding adf to your acf.
Feeding crickets is actually highly entertaining, I just dump a few in and they pluck them from the water surface.
