Frozen bloodworms, freeze-dried bloodworms, frozen brine shrimp, frozen squid, frozen scallops, frozen Daphnia, frozen beefheart (treat), freeze-dried tubifex, and freeze-dried krill.
Herbivores (and some omnivores, because they're pigs =P) get nori, zucchini, and cucumber. For the smaller omnivores I soak the nori and crumble it into flake-sized bits.
My livebearer fry get liquid foods, frozen brine shrimp, and a prepared food called "Micro Gram." I also give "Micro Gram" to adult guppies, neon tetras, and any small labyrinths that are hanging around. On a side note here- I tried pouring a bit of Cyclop-Eeze (a saltwater aquarium food) into my current guppy grow-out tank and the little things went mad for it. May be worth some further experimentation!
My catfish all greatly enjoy Hikari algae wafers and shrimp pellets- the loaches also relish the shrimp pellets as well.
In the Spring and Summer I supplement everything with earthworms, small spiders, and insects from the garden.
Lastly, I do sprinkle in Omega One Freshwater Flakes every now and then- that's actually the favorite of my angelfish. Whereas they will sit back and eye all of the more expensive stuff for almost as long as it takes for it to fall to the bottom, they immediately attack any flakes in the vicinity.
