Origin[edit | edit source]

Found in slow-moving rivers, lakes and canals in Asia, from Thailand to Indonesia, including Myanmar, Bangladesh and India. Juveniles can be found in mangrove forests.

Male has yellow on his tail as well as a modified pectoral fin, and females do not.

Breeding[edit | edit source]

Live bearers. Female will release fry after 3 months.

Tank compatibility[edit | edit source]

Do not keep more than one male Halfbeak per tank. Should otherwise be relatively peaceful and suitable to be housed with other peaceful community fish including Platys and Guppies.

Diet[edit | edit source]

Can be weaned to many different kinds of food, but enjoy brine shrimp, and small insects such as flies.

Feeding regime[edit | edit source]

Feed once or twice a day.

Environment specifics[edit | edit source]

Needs many hiding places on the top of the tank like floating plants (ex. Elodia). The tank should be long and spacious.

Behaviour[edit | edit source]

Mainly occupies the top levels of the tank. The males will fight to the death with other Halfbeaks. Females don't fight as much as males.

Identification[edit | edit source]

Looks like a Silver Needle Nose Gar, only much smaller, and only has half of a beak. A very slender and elongated fish.
