Carnivorous fish eat a high-protein diet. Carnivorous fish eat invertebrates like insects, snails, and worms. Piscivores are a sub-class of carnivorous fish because they will eat mainly other fish and not invertebrates. Trout, Yello Perch and Piranhas are all considered carnivorous. Fish feed pellets are the popular feed in modern commercial fish farming
Some fish feeds are top-rated for carnivorous fish, including Tetra Bloodworms Freeze Dried and Hikari Sinking Carnivore pellets. These products are all available online at Amazon.
Carnivorous feeds are species-specific. If you have only one species of fish, this feed would work well. It won't work if you have more than one species of fish. www.floatingfeedmachine.com
