Hi, I just got two little African clawed frogs and need advice on what to feed them. I've been giving them bloodworms, but wanted to get some pellets to just have around when I can't get live food, etc. I bought some Tetra "Reptomin." However, I've noticed that there is ethoxyquin listed as an ingredient and I know it's an awful preservative for dogs, people and cats, so I certainly want to give it to my frogs! Anyone have any advice on a better alternative with more natural ingredients?
