A buddy of mine shared this recipe with me when i got discus. thanks wesleydnunder!
1 beef heart
1 pound of peeled shrimp
1 pound of white fish fillets
1 pound fresh spinach
8 Centrum multivitamins
1 cup spirulina powder
1 cup flake fish food
1 cup carrots
1 medium zucchini
1 can of green beans
Trim all fat and gristle from beef heart and cut into cubes. Place multivitamins in a small dish of water to dissolve fully. Cut carrots and zucchini into 1/2 inch pieces. Steam carrots, spinach and zucchini until soft, but not mushy. Separately grind beefheart, shrimp and fish either with benchtop grinder or food processor. If food processor is used, be careful not to grind too small. Run steamed veggies and green beans through food processor, again being careful not to make a puree--small pieces around 1/8" are desirable. In a large bowl, mix all ingredients thoroughly. Spoon mixture into quart-size freezer bags and distribute throughout the whole bag, purging all the air possible out of the bag. Press flat. I put enough of the mix in the bag so that it is 1/8" to 1/4" thick. Place bags of food mix in freezer.
When i get ready to feed, I break off a piece and drop it in the tank frozen. It thaws quickly. It is messy and you have to feed sparingly at first to see how much your fish can eat. Vaccuum out any leftovers, unless you have a bazillion MTS in your tank like I do. I've experimented with this recipe over the years, adding this and that. If it turns out too muddy-looking, I add some paprika to give it a red color. I've also tried garlic powder in the mix but my discus don't care for it so I didn't include it this time.
