Honestly, I think it is based on the frog, TJ. My male, Kadesh, is only 2 1/2 years old, but usually chooses to only eat 1-2 times a month. He is also the most inactive out of my three. My other male, Gherkin, is almost 8 years old, and has weekly or more feedings; he is the most active. My female, Obi, is the same age as Kadesh and she prefers to be feed once a week, or once every other week. Despite his infrequent feedings, Kadesh is still a good size, great colouring and hisses at me whenever he is disturbed. Being a relatively non-active frog (especially in captivity), we want to feed them more than they actually need for their lifestyles. As the owner of several overly chubby frogs and toads, I worry when something is not eating when I want it to!!
