Malayan Halfbeak (Dermogenys pusilla) is a slim surface-dwelling livebearer for keepers who enjoy unusual behaviour as much as colour. It spends most of its time just under the surface, so a covered aquarium, floating plants and calm feeding areas are more important than heavy bottom decor.

Quick facts

Scientific name Dermogenys pusilla
Adult size 6-7 cm
Minimum aquarium 80 litres or larger
Temperature 24-28 C
pH 7.0-8.0
Temperament Peaceful surface livebearer; males can spar, so space and cover matter
Diet Surface feeder; small floating foods, live or frozen insects, crustaceans and fine prepared foods

Care and setup

Keep this halfbeak in a mature aquarium with steady, slightly alkaline water and a close-fitting lid. It is peaceful with calm community fish, but males may spar with each other, so give the group room and broken sight lines at the surface.

Avoid boisterous fin nippers and very small fry-sized tank mates. Floating plants help the fish feel secure and make feeding easier.

Feeding

Feed from the surface with small floating flakes, micro pellets and live or frozen foods such as daphnia, mosquito larvae and baby brine shrimp. Offer small meals so food is taken before it sinks away from them.

Arrival and guarantee

Livestock orders are packed carefully and sent by licensed live-animal courier. The Live Arrival Guarantee applies when the receiving and acclimation instructions are followed.
