Not as easy to digest as not a natural meat for fish. I used to make it and did not see enough super growth to mess with it over a good pellet. Better recipe uses salmon and some green like peas or spirolina.
They need some sort of green in diet. I have used peas.. even spinach in my mix. Didn't use gelatin and put mine in syringes to when thawed just squished a little into each container. the fish loved it. got too many water changes to make it now and it funks up water real fast. must do a water change after feeding.
