Holopristis ocellifera
A small characin with reflective red-gold marks above the eye and at the base of the tail, which look like two lamps and give it its name. Hardy, peaceful and easy to keep in a group.
Holopristis ocellifera is a small characin ranging widely from Guyana to the Amazon basin in Brazil and Peru. FishBase gives 4.9cm TL, pH 6.0-8.0, 5-19 dH and 22-26C, while Seriously Fish gives 24-28C, pH 5.5-7.5, 5-20 dGH and a base of at least 60 by 38cm, about 68 litres. Reflective red-gold marks sit above the eye and on the caudal peduncle, and their lamp-like look is what names the fish. It shoals in slow rivers and floodplain lakes, and males are smaller and slimmer than females. It is prolific and breeds readily in the aquarium. Almost every fish on sale is farmed, much of it from eastern Europe, and an albino strain is widely available.

Seriously Fish suggests a base of at least 60 by 38cm, about 68 litres. An ordinary planted community tank is fine, and a dark substrate with wood and floating plants makes the reflective marks stand out.
Seriously Fish gives 24-28C, pH 5.5-7.5 and 5-20 dGH; FishBase gives pH 6.0-8.0, 5-19 dH and 22-26C. Farmed fish are adaptable and untroubled by anything short of extremes.
One of the easiest tetras for a general community, mixing with livebearers, danios, rasboras, other tetras, Corydoras, small loricariids, gouramis and dwarf cichlids. Avoid anything big enough to eat it.
FishBase records worms, small insects, crustaceans and plant matter in the wild. It eats almost anything offered, and frozen bloodworm, Daphnia and brine shrimp alongside dried food improve the colour.
FishBase calls it very prolific and easy to breed in the aquarium, with eggs hatching quickly at 26C. Spawn them in a dimly lit separate tank with fine-leaved plants or a mesh base and take the adults out afterwards.
FishBase lists it as IUCN Least Concern, not on the CITES appendices and harmless to people. A population lacking the red caudal mark has been treated as the subspecies H. ocellifer falsus, but its validity is questioned.
