Natural habitat

Hengeli Narrow Rasbora inhabit still, heavily vegetated waters in Southeast Asia, particularly in Thailand and Malaysia. These environments provide ample cover and food sources, supporting a diet that includes small live or frozen food.

Where they are found

Trigonostigma hengeli is native to Malaysia and Borneo, often inhabiting forested areas with shaded waters that are rich in leaf litter and plant matter.

Aquarium care

To care for Hengeli Narrow Rasbora, maintain a well-planted aquarium with stable water conditions, including a pH between 6.5 and 7.5. Use gentle filtration and create an environment similar to their natural habitat with driftwood and fine substrate.

Feeding

Glowlight Rasboras will thrive on a varied diet that includes high-quality flakes, pellet food, and occasional offerings of live or frozen foods such as daphnia or brine shrimp.

Compatibility

These fish are peaceful and best kept in community tanks with other small, non-aggressive species. Compatible species include other small rasboras, tetras, and corydoras. Avoid keeping them with larger, more aggressive fish, as they can become stressed.

Breeding

Breeding this species is a bit challenging as they scatter their eggs on the undersides of leaves, similar to Harlequin Rasboras. Ensure good water conditions and the right environment to encourage breeding.
