The iPond is an iPod accessory the combines a speaker with a tiny aquarium. A single fish lives in about 650 millilitres of water. It's all the rage in Australia, but some consider it animal cruelty.
RSPCA spokesman Hugh Wirth said despite the fighting fish's ability to breathe air from the surface, the tank was far too small for it to receive adequate oxygen. The small volume of water would lead to rapid temperature change and this meant the tropical fish would not live long, he said. "The iPond should be banned", Dr Wirth said.
