Scientific Name: Neogastromyzon crassiobex (Tan, 2006)

Common name: None

Distribution: Borneo

Sexual Dimorphism: Unknown

Maximum size: 2 inches (5cm)

Similar to: Gastromyzon and other Neogastromyzon species

Neogastromyzon crassiobex

Care: Inhabit fast flowing highland streams over boulders. Aquarium must duplicate these conditions as fish have very high oxygen requirements.

With all sucker-type Hillstream species, care is broadly the same. All need excellent water-flow and aeration, numerous rocky hiding places and smooth pebbles and boulders to graze over. Lighting should be bright to encourage algal growth in the aquarium. Plants are not necessary as the fish do not normally encounter them in the wild, but they will help with water-quality. Suitable plants for high-flow environments are Anubias and Microsorium. These will grow on rock-work or driftwood.

See: Hillstream Loaches: The Specialists at Life in the Fast Lane for more detailed explanation.

Feeding: The diet in aquaria would probably consist of bloodworms and brine shrimp as well as algae.

Water parameters: pH:7.0-8.0 Hardness: Medium Max dh: 12

Temperature: 70ºF to 79ºF (21-26°C)

Breeding: Not bred in aquaria


This newly described species was formerly thought to be Neogastromyzon pauciradiatus and is not known in the pet trade at this time. N. crassiobex, as well as other Neogastromyzon species, might show up as a contaminant in shipments of Gastromyzon species found in the same waters.
