He gets one serving of a fruit or vegetable every day. For my gel food, the recipe varies but it's usually a mix of shrimp, scallops, salmon, cod, tilapia...whatever fish is on sale at the market, spinach, peas, bananas, vitachem and naturose astaxanthin. I don't use all those ingredients at the same time as I make enough food for the week and alternate so he doesn't get the same thing every week. Throw everything in a blender, add some gelatin and freeze. It does get a little messy but hey, if it's good for him, I don't mind keeping up with the tank maintenance!
