I am interested in this. Perhaps you could do a write-up and ask a mod to sticky it?
It's not really an EXACT science. I've done a lot of trial and error. Depending on the type of fish you want to feed, you can change the formulation to meet their needs.
I use canned fishes (mackerel, sardines, anchovies, salmon) and different greens and vegetables. If you have strict carnivores you would use more meaty foods and less of the roughage. Different types of squash, zucchini, kale (a very high vitamin content, I even feed a small amount to my carnivores) mustard/collard/turnip greens. I've even used bell peppers!
I'm lazy, so I buy all the greens and vegetables I'll need for a few batches, and what I don't make in the first batch, I freeze til I'm ready to make a new batch.
Here's a more in depth explanation on a goldfish forum, the only difference is, most of our fish have less vegetables and more MEAT in their diets

I fed my toadfish some gelfood, and she ate the crap out of it! That recipe was salmon, anchovy, sardine, kale, spinach, bell pepper, spaghetti squash and zucchini.
More recently, I've been shopping at the asian market to buy frozen fishes, and will begin trying to broil/steam the fish and use that instead of the canned fishes, so I can vary their diet more. Tilapia, octopus, pollock, cod...the possibilities are ENDLESS! The only reason I would cook the fish in the gelfood, is to prevent it from spoiling in the fridge before the fish eat it.
