I'll have to go back and edit my profile. I'm an American, but I live in Costa Rica. I looked over some of the things people are feeding these various frogs, but the problem is that I have no access to any of them. I asked at my vet clinic, and they just sell fish food and iguana food, but nothing for any frogs. I guess I will keep them for the time being. I have one that left the water yesterday and still had a really long tail. Today he is more green and has a shorter tail. He'll probably leave the aquarium either tonight or tomorrow morning. Then he can eat what he wants. Thanks Cheri and Poly for your help. I feel better knowing that I'm not hurting them feeding them fish flakes.
