Similar to the South American arowanas in basic shape, but with a smaller mouth that is not turned upwards. The dorsal and anal fins are long, but unlike the situation in South American arowanas, they do not merge with the tail fin.

Fish information (behaviour and breeding):

Omnivores, these fish eat a variety of foods but to a large degree are filter feeders, sifting out plankton from the water or small invertebrates from the substrate. In captivity they like to root about in the sand, pumping water through their gills and capturing prey such as bloodworms and daphnia.

Aggressive towards their own kind but otherwise peaceful, this fish can be kept with other large, robust species.
