Mexican Walking Fish (Axolotl) – Wired’s Pet For Geeks
The Mexican Walking Fish or the Axolotl is, according to Wired, probably the ultimate geek pet.
This gilled amphibian which spends most of its time in water is delightfully alien looking and offers a great attraction to visitors. Axolotl will also happily share a tank with fish and others, making them a feature pet for any aquarium. Contrary to popular opinion (mainly because they have legs) they don’t need access to land in the same way frogs do. They can survive quite happily in a tank with no access to land and spend a lot of time down the bottom of the tank. They do not need to “sun” themselves like turtles.
The axolotl, an aquatic salamander native to Mexico, is colloquially known as the “Mexican walking fish” (or wooper rooper if you are in Japan), although it is not a fish. And contrary to the Wired article, beware of which fish you keep in the same tank – you might just find some of them missing. Here’s a video from YouTube:
