I decided to try my hand at making some food for my fish. They are all omnivores, so after a little research and an inventory of what I had on hand, I ended up with spinach, broccoli, peas, winter squash, blue green algae, worms, shrimp, and whitefish filets. Puree, press out the water, and freeze. The fish seem to like it, but I'm a little worried that I may be missing something vital and alternate with flakes. Any thoughts?
