Actually, activated yeast is what we feed to brine shrimp if/when we want adult brine shrimp of a week or two of size for some of the larger-than-baby fish.
The food I made included:
Spinach (half a bag, but the bag was about the size of an 8x11 sheet of paper, I think)
4 oz. Crab meat from a can
2 packets (about the size of a wallet-sized picture)
unflavored gelatin
about 8 oz water
a whole frozen fish (tilapia in my case, but next time will use boneless fillets.. the bones that I didn't find to pull out didn't grind well)
1 medium zucchiniabout 30-40 malaysian trumpet snails (shells were for
calcium, but the shells didn't grind completely for me.. so I may skip that next time)
about a palm full of duckweed (more plant matter there)
Salad shrimp, about half a bag..
maybe 4 oz?
2 large cloves of garlic that I had leftover (it was roasted, but left unused from a pasta dish, so it got frozen until I used it in this food)
(I think that is everything I put in it.)
I would use spinach rather than lettuce, mainly because lettuce is mostly water, whereas spinach is a healthy dark leafy green.
