The Axolotl (or "Walking Fish") are very popular pets for an unheated aquarium or large bowl. They mainly feed by smell as they have poorly developed eyesight, earthworms being one of their favourite foods. If kept with fish, ensure the fish do not bite the axolotl's gills, and alternately, not be small enough for the axolotl to eat them. The Axolotl is a neotenic amphibian: unlike related species they do not metamorphose into a salamander, instead remaining/breeding in the "juvenile" stage. They can grow to about 20-25cm and are also able to regenerate damaged limbs and gills.
