Overview
The zebra Borneo sucker is a hillstream sucker that lives clamped to rock in fast water. It suits a mature, fast-flowing tank and is for experienced keepers.
Did you know
Borneo suckers come in many patterns across different rivers, whether spotted, marbled or plain. The zebra Borneo sucker, from the Sambas, wears bold zebra bars, one drainage's own take on the family look.
Caring for the zebra Borneo sucker
Give zebra Borneo suckers a mature tank of 24 gal (90 L) or more. Line the bottom with smooth stones, left to grow a natural film of algae under strong light. Plants matter far less than strong flow, high oxygen and clean water. Keep the water at 72 to 79°F (22 to 26°C) with a pH of 6.5 to 7.5.
The zebra Borneo sucker grazes the bottom all day. Its survival depends above all on a mature, living film of algae and biofilm. Occasional frozen meaty foods are fine, but too much protein harms it.
It is a peaceful, social fish, best kept in a small group of at least three or four. It mixes well with other calm current lovers, such as small rasboras, danios, gobies and fellow hillstream loaches. It is not known to have bred in home aquariums.
Good to know
The zebra Borneo sucker is a hillstream loach in the family Gastromyzontidae. Its fused, wing-like fins clamp its flat body to rock and let it hold position and graze in fierce current. The name refers to the crisp pale bars over a dark ground that give it a zebra pattern. It is also known as the Sambas Borneo sucker and the striped Borneo sucker.
In the wild
Gastromyzon zebrinus is known only from the upper Sambas basin in West Kalimantan, on Indonesian Borneo. It lives in swift, shallow streams saturated with oxygen, among riffles and cascades.
