|pH||5.4 - 7.6|
|Temperature||20.0-27.0°C or 68-80.6°F (Show species within this range)|
|Other Parameters||Hefty filtration is required to clean-up after this greedy fish.|
|Feeding||Simply anything digestible it can fit into its mouth. Will therefore take all normal aquarium foods.|
|Furniture||Not really an aquarium fish. Although largely inactive and so doesn't require a great deal more room than simply to turn around do bear in mind though that this fish can easily reach the size of 1m in captivity.|
|Compatibility||Will attack surprisingly large fish often with fatal results, a greedy, voracious predator. One for a species tank.|
|Breeding||During spawning, the male first follows the female, swimming with the head against the side of the female, interspersed with periods of solitary swimming or inactivity). The pair then swim head against head with the male on top. This is followed by the male folding the body first around the head, and then the body of the female. During the latter stage, eggs and sperm are released. The female then pushes her head into the substrate and beats her tail vigorously, mixing the eggs and sperm.|
