Common name:

Blue green lampeye, Bluegreen lampeye


    Niger and Benue rivers, Nigeria. Also known from Cameroon. Cross system and coastal rainforest.

General Body Form:Male: A deep-bodied fusiform shape with a rounded belly. Fins are moderate-length and generally rounded. Caudal fin is truncate. Fins may lengthen with age. Short snout with dorsal mouth. Opercula is rayed. Female: Smaller than males, without fin lengthening.

Coloration:Male: Silver body with blue-green iridescence. Fins appear azure and are delicately rimmed in red. Anal and dorsal fins have a series of red spots basally. Caudal fin is almost completely covered in red spots with the exception of the most posterior quarter. Eyes are a platinum white-yellow. Female: Colors are more pale than in males.

Maintenance:Difficult. Needs very clean, highly-oxygenated, well-filtered water. A powerhead may be used to simulate a riverine current. To help replicate their native environment, choose a soft sand or small, rounded gravel substrate, plant heavily around the aquarium margins and leave a large, central area of open swimming space. A very peaceful shoaling fish that fairs best in a species-only aquarium, but adapts to a lightly populated community aquarium as with similarly-sized, peaceful tankmates.

Diet:CARNIVORE: Enjoys live or frozen artemia, bloodworm, brine shrimp nauplii, vitamin-enriched brine shrimp, white mosquito larvae as well as flake food.


Biotope:Flowing areas of small rivers and brooks.

Breeding:Difficult. OVIPAROUS: Egg-laying crevice-spawners. Sexual dimorphism/dichroism: Males are larger and more brightly colored than females. Also, the anal, caudal and dorsal fins of males may elongate with age. Fish being considered for spawning should be conditioned on a diet of high quality foods with an emphasis on live and frozen proteins for at least two weeks prior to spawning attempts. A spawning tank is highly recommended and easily established. The tank should have a bare floor, gentle sponge filtration and low lighting. For crevice spawning, provide clumps of java moss, spawning mops secured with rubber bands to narrow the gaps between yarns or filter foam in which eggs can be laid. Fry hatch in 10 – 14 days (hatching faster in slightly warmer water) and initially will accept infusoria the first 3 – 4 days, followed by Artemia nauplii , crushed flake food and microworm. These fish grow slowly and will swim mostly head- up for the first few months as this helps them find food in nature.

Diseases:Not overly susceptible to any of the more common diseases and parasites. Like with all fish proper precautions should be taken.
