FYI some of the major frozen co. add gelatin to their food. I use a homemade food from a well known LFS that use gelatin and shredd it like cheese. It helps hold it together. Here is what is in theirs.
Our food is a 20 year improvement over a public aquarium gelatinized diet first called "The Mystic Aquarium Diet" A powdered salmon diet is the base with broccoly and carrot for HLLE avoidance, white flesh fish, shrimp, blended w/shells, Spirulina powder, astaxanthin for color enhancement, Knox brand gelatin, multivitamins, raw eggs, shell and all blended and a few other goodies, always blended fresh by myself. Good enough that our clowns breed without add'l feeding on it and we also feed it to our Corals. ----
Note. You still need to freeze it to preserve.
