Overfeeding? Underfeeding? Or something in between?

Sorry. I just thought I should elaborate on something. The chubby frog only appears to be SLIGHTLY chubby and only when he's got his legs tucked. When he's moving around the tank, he looks great. The thin frog does not look emaciated or anything. He is just thinner than the others. He actually looks right when his legs are tucked. He mostly only looks thin when he's hanging out in the pool with his arms and legs stretched out.

I had two Grays myself, and currently have a Green Tree Frog (american) that is very similar in care (just a bit warmer and humid than the Grays). I used to feed my guys 2-3 crickets every other night, but have since decided that with my new little guy, I'd rather give him a bit of a full belly than an empty one, and give him 3-4 now (dusted with Calcium+d3). I could also recommend tweezer feeding if you haven't attempted already, but that could still prove to be something they won't want to do until they are used to it, yet will help with managing feedings.

Did they do well on that diet? Mine just always act like they're starving. Even the one that wouldn't eat at first has joined the others in making me feel bad. I just want to make them as happy as they can possibly be in captivity. At the same time, I don't want to trade happiness for health and longevity. I know they would eat more if given the opportunity, but don't want to knock even a month off of their lives by feeding them incorrectly. I am dusting their crickets about twice a week. I didn't mention that before.

I have used tweezers, but only with the one that wasn't eating. My husband would hold him while I forced his mouth open with a card in one hand and placed the cricket in his mouth with the tweezers from the other. I haven't tried feeding them voluntarily with the tweezers. The way I'm feeding is to lay out three sterilite style containers, put the crickets in, then put the frogs in with them. This has actually been the best method for me personally because it gives me a chance to clean the tank without worrying about a frog escaping or getting smashed by a rock when I move it. It also gives the frogs a chance to do what they do. They don't get to stalk their prey through the night or anything, but at least they get to pounce on the crickets. Sort of a compromise. Everyone in my house loves watch them. I don't get to often because I'm running around trying to get the tank back together before they finish, but I love to when I can.

I started doing it this way because on the first night, I removed about half of the plants and things so they could see the crickets better. I put six crickets in the tank. Frog 1 ate three as soon as they entered. Frogs 2 and 3 didn't even make it down from their perch before two of the crickets jumped in the water and drowned. Stupid kamikaze crickets. The last cricket squeezed in between a rock and the glass, was dead the next morning.

If you get a small pyrex style glass bowl and affix it somewhere in their enclosure were frogs can reach, only need to place crickets in it. Crickets can't climb out and they don't even try to jump either. That way you can: monitor whose feeding; how much; and end their possibly stressful handling. Works for Dubia roaches too and can feed dusted insects right from it. Some of those bowls have two little handles and the frogs can sit on them while they feed. Good luck !
