Fish Food and Feeding (Cont.)
Fresh romaine lettuce is popular food with many Central American cichlids, mbuna, and Tropheus cichlids. Pacus, silver dollars, plecostomus, goldfish, and koi enjoy grazing on romaine lettuce daily.
Zucchini is a popular food for plecostomus. It can sliced and served fresh or blanched. Some hobbyist remove the skin before feeding, but others remove the skin from the tank once the flesh has been eaten.
Beef heart is an excellent food for many fish. Young fish that are fed beef heart grow rapidly. You can buy beef heart already prepared for feeding to the in frozen packs (usually in cubes), or you can prepare your own from the beef heart you can buy at the supermarket.
Nori seaweed that is used to wrap sushi is an excellent food for many species of freshwater fish. Many cichlids will eat nori, as well as livebearers. It is a excellent food that is about 1/3 protein and provides many vitamins.
Swordtails as well as other livebearers can all benefit from nori seaweed being part of their diet.
