When choosing which type of fish feed to use, aquarists can either select a staple diet suitable for all creatures living in the aquarium, or a specialised feed that is specifically designed to meet the requirements of certain species of fish. TetraMin, TetraPro and TetraNatura Mix are readily accepted by all types of tropical fish. The sinking properties, size and composition of these specialised foods have been developed to precisely match the feeding habits and requirements of the type of fish in question to offer these animals an appropriate form of nutrition, using feeds such as TetraCichlid, TetraDiscus, TetraGuppy or TetraBetta. Recommended feeds for fish living at the bottom of the aquarium include TetraTablets TabiMin, Tetra PlecoMin or Tetra WaferMix. Feed tablets and wafers sink rapidly to the base of the tank, where they can be instantly picked up by catfish or loaches.
