Livebearer · Moderate
Livebearer giving birth every 4-6 weeks to large young (up to 2.5 cm). Mothers readily eat their young; good results need a varied diet including small insects.
A male with 2-3 females.
Planted 100 L tank with hard water and floating cover.
Warm, clean water and live food.
About 9-11 young per brood, every 4-6 weeks.
Fry accept baby brine shrimp and fine flake.
A stocky halfbeak from streams of the Maros highlands, South Sulawesi. Unlike Dermogenys, its upper and lower jaws are about equal in length, and males can carry a fleshy hook on the lower jaw. It needs cooler water (20-24 °C) than most halfbeaks.
Dietrich Vogt described this halfbeak in 1978 from southern Sulawesi. It is a colourful livebearer with a short beak and dark-tipped fins.
First described by Dietrich Vogt in 1978.
