OMG, 5 gallons…you must have a large freezer.
I decided to try this recipe because it resembled other recipes and I was guided by some things I read on the Florida Aqua Farms site. This recipe makes a convenient amount of food to store in my tiny freezer. The cubes are easy to cut, so I can feed a quarter cube to my fish if I want, or defrost one or two cubes to feed a crowd.
This is what I did last time:
I bought a bag of mixed frozen seafood at the Asian grocery store , $6
I bought gelatin and cod fillet at the usual grocery store, kelp at the health foods store, and I already had freeze dried spirulina fish food by Ocean Nutrition that I used in place of spirulina. Kelp and Naturose were the most expensive ingredients, but I have enough to make more food next time.
I waited until the family was going to be out of the house, on a day when I could open the windows, and use the automatic dishwasher.
I rinsed out the food processor to make sure there was no residual soap in there, and attached the fine grating attachment. Then I grated the following frozen items picked from the mixed seafood bag:
18 grams shrimp
17 grams mussells and or clams
20 grams squid
20 grams scallops
and 30 grams cod fillet, previously frozen from the grocery store,
and put this mixture back in the freezer.
I heated about 1/2 cup non-chlorinated water to boiling in the microwave, and dissolved a packet of gelatin. This took some stirring and reheating to accomplish.
When it had cooled to approximately 37C, I mixed in the
4 grams spirulina food,
2 grams dried kelp
5 grams naturose
and it formed a dry-ish paste. Then I mixed this with the frozen grated food in a plastic freezer bag, kneading it in the bag until it looked uniform.
I sprayed some squares of egg crate with Pam, set them on small sheets of plastic, and mashed the food into the squares with a spatula and my fingers. The food in its egg crate was slipped into ziplock freezer bags, and frozen.
This food pops off the egg crate with ease, and my fish seem to love it. I would like to give this food credit for my newest spawning pair, but I think I am feeding more often and more reliably now that I am unemployed. It does give my orange clownfish great color, and its true that fish who had stopped spawning because I cleaned their tank, resumed while this diet was available to them.
When I make it again, I want to try doubling the gelatin/water quantities to see if I get a more cohesive mixture. Right now the stuff falls apart when it hits the water and thaws.
The size of the particles is very small, so I may try grating half of the frozen mixed seafood on the fine grater, and use the next size bigger for the rest of the food.
