Acestrorhynchus falcatus (Freshwater Barracuda)
A large, silvery fish with big eyes and a reddish tail fin. Juveniles tend to be rather long and cigar-shaped, while adults fill out a bit and look more robust.
These fish are out-and-out predators, and in the wild feed primarily on smaller fish. Weaning juveniles onto dead foods or alternatives such as mealworms is possible, but adult fish tend to be much less tractable.
Fish information (behaviour and breeding):
Although not infrequently offered for sale, these are difficult fish best left to experienced aquarists. A very big aquarium (at least 600 litres) is required to maintain a group of these fish, and water quality must be excellent.
These are open water fish, and in captivity are prone to swimming into the glass, so use plants and decorative items such as bogwood to create obvious 'boundaries'. Can be kept with suitable tankmates (e.g., plecs) but avoid anything aggressive, because these fish are nervous and panic easily. They can jump, so cover the tank!
Only rarely bred in captivity. These fish are egg scatterers, and offer no brood care. The eggs hatch after about a day and require small live foods such as infusoria and newly hatched brine shrimp.
