Features

Pet fish are marine vertebrate animals. They are enveloped with scales and have two pairs of matching fins and a number of unmatched ones. Fish use gills to breathe--oxygen is extracted from the water that enters through their mouths and is then forced over the gills, which extract the oxygen from the water.
Considerations

Anyone thinking about owning pet fish must consider the required upkeep. The regular maintenance needed differs depending on the size of the aquarium (or bowl) and the specific breed of fish.
