纹唇龙嵴鲀

Overview

Endemic in known records to Sarawak, Carinotetraodon salivator has dark head and body bars in both sexes and a pale lower-lip mark. Collection sites include flowing streams, suggesting that some water movement may be appreciated rather than an entirely still setup.

Distribution & habitat

Records come from the Lupar, Sarawak, and Rajang systems. Fish have been collected around shallow margins among leaves and submerged roots. Sites range from silty or sandy channels with rocky riffles to clear forest runs and faster blackwater draining peat swamp.

Aquarium setup

Start with the suggested minimum dimensions of 60 by 30 by 30 cm. Dense planting, wood, roots, and floating shade provide cover; leaf litter supports small food organisms as it matures. Allow some circulation while prioritizing stable, clean water and frequent small changes.

Diet & feeding

Regular small shelled invertebrates help control dental-plate growth. Supplement these with chopped shellfish, small earthworms, and suitable live or frozen prey. Dry products should remain secondary, although very hard pellets may be useful. Retaining biofilm allows for its possible contribution to natural feeding.

Behaviour & compatibility

Although less aggressive than some relatives, it is still best housed alone. Any peaceful schooling companions must be large enough to avoid predation without becoming threatening competitors. Social grouping is loose, and males tend toward territorial behavior; several fish require generous cover and space.

Sexual dimorphism

Male dorsal and ventral keels rise during displays. Their undersides are red with anterior crossbars; females have cream-colored undersides with dark stripes.
