Give your fish a treat! Flaked fish foods are excellent nutritionally, but most fish really enjoy tucking into live, or frozen live foods. Insect larvae such as bloodworms can be collected in summertime from your water barrel, but it is also very worthwhile to attempt to culture Daphnia or white worms for a free food source absolutely relished by aquarium fish. Frozen bloodworm are almost as good and are widely available, though freeze dried live foods tend not to go down as well. See more on feeding fish
