Tablets

Fish food is plant or animal material intended for fish kept in aquariums or ponds. Fish foods normally contain the macro nutrients, trace elements and vitamins needed to keep captive fish in good health, and are formulated with specialized ingredients to ensure proper digestion and optimum health.

Approximately 80% of fishkeeping hobbyists feed their fish exclusively prepared foods, most commonly produced in flake, pellet or tablet form. Pellet forms, some of which sink rapidly, are often used for larger fish or bottom-feeding species such as loaches or catfish. Some fish foods also contain additives such as beta-carotene to enhance the colour of ornamental fish. Generally, the more moisture a fish food contains, the more readily it deteriorates in quality.
