Other Types of Discus Fish Foods... Daphnia, needs a bit more work... search on line under raising live Daphnia for all the tricks. The easiest live food to keep is Blackworms. To raise blackworms you simply purchase the amount you need 1/2 or 1 lb portions. Place them in a rubber made container of a 12-16 inch diameter with a 4 inch height with around 2.5 inches of cool (60-75) degree de- chlorinated water. Some people keep them in the fridge, I on the other hand keep them in a cool shaded area outdoors. The worms will need to be rinsed off every day or so with freshwater.

This greatly depends on the water temp and amount of worms you have. To rinse them, simply tilt the container at an angle so that all of the worms conglomerate together then pour off the old water and add new fresh water. These worms will last for weeks with no food necessary for them. If you do have them for an extended period or want to fortify them, you can feed them a small amount of fish food in the flake or pellet form, organic material such as spinach leaves or romaine also works. Just be careful to feed sparingly as you are likely to foul the water and jeopardize the health of the worms...The blackworms we carry are farm raised and are not loaded with bacteria and other harmful pathogens that can be found in sub standard suppliers.
