(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

Fishkeeping Facts and Tips

Should I have water movement in my tank? Fish from faster flowing rivers love swimming against a current - fish from vegetation choked marshes do not. With todays box filters it is quite easy to get some good water flow for strong swimmers like Rainbowfish, whilst a spray bar attachment can completely remove this for gentler swimmers like Gouramis
