The Apple iPond is a speaker for your iPod that also doubles as a "fish tank" for aquarium fish, mainly Bettas because of their limited space requirements (but not that minimum.) Total capacity of the tank is right around 650 millilitres. For comparison purposes, 650 millilitres = 0.171711833 US gallons.
