(Other members of the genus Dermogenys)

ADULT SIZE: 10 cm

WATER CONDITIONS: Not critical

TEMPERATURE RANGE: 23-27 C

FOOD: Feed Dermogenys pusillus live and dried foods. As a surface feeder, live flightless fruit fly (drosophila) make an excellent treat for these fish.

DISTRIBUTION: This species comes from Indonesia, Malaysia, Thailand

AQUARIUM CARE: The half beaks are charming surface dwelling fish that are prone to fight. They are difficult to keep as they will fight, jump, and damage themselves by slamming into tank sides if scared. They are best kept in a well planted tank with surface vegetation. A challenge even for the most experienced aquarist.

BREEDING: A difficult livebearer that often suffers in captivity. Good feeding is essential to sucessful breeding, including insects, fruit flies etc
