Oliotius oligolepis
A small barb whose scales each carry a black crescent, giving a chequered look, and which has notably large, few scales. Very peaceful, and males colour up as rivals compete in a group of six or more.
Oliotius oligolepis comes from Sumatra in Indonesia. FishBase records a maximum of 5.0cm TL, pH 6.0-6.5, up to 10 dH and 20-24C, and places it in creeks, rivers and lakes feeding on worms, small crustaceans, insects and plant matter. Seriously Fish gives 45mm SL, 18-25C, pH 5.5-7.5, 2-12 dGH and a 75 x 30cm base of about 68 litres. Every scale carries a black crescent, and the scales are unusually large and few, which is both the diagnostic character and the source of the chequered look. Very peaceful and well suited to a community, it colours best in a group of six to ten as males compete. It is farmed commercially in huge numbers and wild fish are hardly ever traded. Carried worldwide, it has been recorded from natural waters in Colombia. The IUCN rates it Least Concern and it is not listed by CITES.

Seriously Fish suggests a 75 x 30cm base of about 68 litres. Decor is not critical, but floating or overhanging plants and driftwood improve both colour and confidence.
Seriously Fish gives 18-25C, pH 5.5-7.5 and 2-12 dGH, while FishBase records pH 6.0-6.5, up to 10 dH and 20-24C. Its natural water is soft and acidic, so avoid hard water.
Very peaceful and easy to combine with small fish of similar size. Seriously Fish advises buying at least six to ten, which reduces skittishness and sharpens the males' colour.
An omnivore taking worms, small crustaceans, insects and plant matter. It feeds readily on dried food, and frozen bloodworm or Artemia keeps it in better condition. Its mouth is small, so choose fine-grained foods.
An egg scatterer with no parental care. In good condition it spawns often, and fry sometimes appear unaided in a mature planted tank. Males are smaller, slimmer and more colourful than females.
A widely available beginner’s fish, almost all of it farmed. It is small with a small mouth, so avoid larger fish that could swallow it. The IUCN rates it Least Concern and it is not listed by CITES.
