Emerald Eye Rasbora (Brevibora dorsiocellata)

Emerald Eye Rasboras are a peaceful and very hardy species of Rasbora, making them an ideal resident of the community aquarium.

These Rasboras have no particular demands when it comes to water chemistry; therefore, you can house them with most of the popular species in the hobby. These can include other small Cyprinids, Tetras, Livebearers and Dwarf Cichlids, as well as Catfish and Loaches.

Emerald Eye Rasboras are a tight shoaling fish that can be rather timid; therefore, it would be better if you kept them in groups of 10 or more individuals. Larger groups will help your fish feel more secure and result in a more effective, natural behaviour. In addition, males will also display their best colours as they compete with each other for female attention.

In the aquarium, the choice of decor is not as important as the water quality. However, these fish look especially effective in a well-planted aquarium with a dark substrate.

Emerald Eye Rasboras thrive in a natural-style set-up with a soft, sandy substrate and a few driftwood roots and branches placed to form plenty of shady areas. The addition of dried leaf litter further accentuates the natural feel. The leaves also offer even more cover for the fish as well as bringing on the growth of microbe colonies as decomposition occurs.

These microorganisms can provide an essential secondary food source for babies whilst the tannins and other chemicals released by the rotting leaves are beneficial for blackwater fish species.

Emerald Eye Rasboras prefer reasonably dim lighting, although this does hinder the use of some aquatic plants. However, Taxiphyllum, Cryptocoryne and Microsorum can all survive in such conditions.

The Emerald Eye Rasbora is an elongated fish with a pointed nose. Their base colour is a reflective, metallic silver; however, the fish can take on a yellowish hue under some lighting conditions, with a slight pink blush present in the central area of the body between the pelvic fins and the operculum. In addition, these fish sometimes display a thin olive gold-tinted parallel line from the operculum to the caudal peduncle under reflected light conditions. All their fins, except for the dorsal fin, are hyaline.

Feeding

In the home aquarium, the Emerald Eye Rasbora will readily accept most good quality dried foods such as granules, flakes and sinking pellets. These modern food products have been developed to provide all adequate nutrition to maintain your fish's health and dietary requirements.

Providing additional foodstuffs such as live, frozen, and freeze-dried meals such as bloodworm, daphnia, and tubifex once or twice a week will provide additional benefits to your fish's health and well-being but is not a must for this fish.

It should be noted that bloodworms should only be given as an occasional treat and should not be used as the staple diet as they are difficult for fish to digest and can potentially cause blockages.

This fish is an omnivore in the wild, meaning it will consume some vegetable matter. Although most modern fish foods take this into account and include them in their products, you can still supplement your fish's diet with blanched vegetables such as spinach, broccoli, and zucchini. Ensure you do not overfeed your fish and remove any leftovers the following day.

Sexual Dimorphism

It is somewhat challenging to distinguish between male and female Emerald Eye Rasboras. However, mature females are generally a little larger than males and are noticeably rounder-bellied. In addition, males can sometimes display a pinkish-red hue on their caudal fin during the breeding season, whilst females do not.
