The Emerald Eye Rasbora (Rasbora dorsiocellata), also known as the Emerald Eye Micro Rasbora, is a captivating and visually striking fish that has become increasingly popular among aquarium enthusiasts. This diminutive species hails from the clear, slow-moving waters of Southeast Asia, particularly in regions such as Thailand, Malaysia, and Indonesia. Renowned for its dazzling emerald-green eyes and vibrant coloration, the Emerald Eye Rasbora has earned its place as a gem in the aquarium world, enchanting hobbyists with its beauty and amiable nature.

Appearance:

The Emerald Eye Rasbora is a small fish, typically reaching a size of around 1 to 1.5 inches (2.5 to 3.8 cm). Its most distinctive feature, as the name suggests, is its brilliant emerald-green eyes, which stand out against the translucent body. The body itself exhibits shades of gold and silver, creating a shimmering effect that further enhances its overall allure.

This species boasts a streamlined body with a forked tail fin and possesses an understated yet graceful presence in the aquarium. The anal and pelvic fins are marked with subtle hints of red and yellow, adding an extra layer of elegance to its appearance.

Habitat and Tank Requirements:

To provide an optimal environment for the Emerald Eye Rasbora, aquarium enthusiasts should replicate its natural habitat. These fish thrive in heavily planted aquariums with soft, slightly acidic water. A dark substrate, dim lighting, and the inclusion of driftwood or leaf litter can mimic the conditions of the slow-moving rivers and streams where they are typically found.

A nano aquarium of at least 10 gallons (38 liters) is suitable for a small school of Emerald Eye Rasboras. Maintaining stable water parameters is crucial, with a temperature range of 72-78°F (22-26°C), a pH level between 6.0 and 7.0, and very soft to moderately hard water.

Behavior and Compatibility:

The Emerald Eye Rasbora is known for its peaceful and sociable nature, making it an excellent addition to community tanks. These fish thrive when kept in schools of at least six individuals, and observing their synchronized movements adds to the visual appeal of the aquarium. They coexist well with other non-aggressive fish species, such as small tetras, dwarf shrimp, or other peaceful Rasboras.

Feeding:

Emerald Eye Rasboras are omnivores, accepting a varied diet. In captivity, a well-balanced diet can include high-quality micro pellets, flakes, and small live or frozen foods like brine shrimp or daphnia. Offering a diverse range of foods ensures that these fish receive the essential nutrients needed for vibrant colors and overall well-being.

Breeding:

Breeding the Emerald Eye Rasbora can be achieved with relative ease in a well-maintained aquarium. Provide a densely planted environment, and the fish will lay adhesive eggs among the plants. The parents should be removed from the breeding tank to prevent them from consuming the eggs or fry. Once hatched, the fry can be fed infusoria or liquid fry food until they are large enough to consume micro-sized live or prepared foods.

The Emerald Eye Rasbora, with its stunning green eyes and captivating coloration, has become a prized gem in the aquarium hobby. Its manageable care requirements, peaceful demeanor, and compatibility with other small fish species make it an excellent choice for both novice and experienced aquarists. Bringing the charm of Southeast Asian waters into the confines of the aquarium, the Emerald Eye Rasbora truly stands out as a radiant jewel in the underwater realm.
