Silver Arowana (Osteoglossum bicirrhosum)
Unfortunately the Arowana still occasionally appears for sale in aquarium shops. Considering that this fish grows up to 100cm in an aquarium, and up to 150cm in the wild, it is obviously unsuitable for home aquariums; shops which stock these fish are acting highly irresponsibly. Do not purchase these fish unless you have an aquarium over 400cm (!) in which to house them. The Arowana is a surface dwelling fish which is tolerant of a wide range of water conditions, they are predatory so can only be kept with other large fish. The aquarium should be covered, as the Arowana are excellent jumpers.
