I make my own gel foods, I can't see what binding agent they use. I don't add any chemicals to mine though besides a vitamin supplement, I use a variety of fresh foods such as prawns, squid, fish, sweet potatoe, carrot, peas, bok choi, lettuce, spinach ect. Pretty much what I have available. Would this be workable? From what age do they feed it? Not sure if it's in the video, I'm at school.
