New Fish Tank Tips: Get the biggest tank you can afford. A larger aquarium generally means that your aquarium water parameters will be more stable. A bigger tank gives you some room for error, like when a fish dies and you don’t notice it right away. Or, for instance, when your heater breaks and the stores are closed. The water temperature should be more stable in a bigger tank.

The freshwater garfish, Xenentodon cancila is the sole member of its genus. It is found primarily in freshwater habitats, though it is sometimes found in brackish water and the sea. It is most common in rivers, but may also be found ponds, canals, and other freshwater habitats.
As a reasonably popular aquarium fish Xenentodon cancila, has been traded under a variety of common names, including needlefish, silver needlefish, Asian freshwater needlefish, needlenose halfbeak, freshwater gar, and numerous others. While belonging to the same family as the marine needlefish known in Europe as gar or garpike, Belone belone, these fish are of course much more distantly related to other fishes sometimes called gars (such as the North American Lepisosteidae and South American pike characins).
The freshwater garfish is widely distributed across South and Southeast Asia from India and Sri Lanka to the Malaysian Peninsula.
In common with other needlefish, this species has an elongate body with long, beak-like jaws filled with teeth. The dorsal and anal fins are positioned far back along the body close to the tail. The body is silvery-green, darker above and lighter below with a dark band running horizontally along the flank. Slight sexual dimorphism exists, the male fish often having anal and dorsal fins with a black edge.
