Danio albolineatus
A small danionin with a blue-green sheen and a pale orange stripe along the flank. Hardy and strongly swimming, it colours up best in a group of five or more. Its one real hazard is jumping.
Danio albolineatus occurs in hill streams from Myanmar through Laos to Sumatra in Indonesia. FishBase records a maximum of 9.6cm TL, a common length of 3.4cm, pH 6.0-8.0, 5-19 dH and 20-25C, and notes that it shoals at the surface of clear streams feeding on insects that fall in and on zooplankton. Seriously Fish gives 55mm SL, 16-25C, pH 6.0-8.0, 1-20 dGH and a 90 x 30cm base of about 81 litres. The pale orange lateral stripe over a blue-green sheen gives the fish its name, and mature males take on red in the anal and caudal fins. It is very peaceful and undemanding about water chemistry, but swims strongly and suits a long tank. It jumps well and is often lost through gaps in the lid. The IUCN rates it Least Concern and it is not listed by CITES.

Seriously Fish suggests a 90 x 30cm base of about 81 litres. It swims strongly, so choose a long tank, and fit a tight lid with no gaps because jumping is the usual cause of losses.
Seriously Fish gives 16-25C, pH 6.0-8.0 and 1-20 dGH, while FishBase records 20-25C, pH 6.0-8.0 and 5-19 dH. It tolerates cooler water well but should not be kept warm year round.
Very peaceful and compatible with similar-sized cyprinids, characins, livebearers, rainbowfish, anabantoids, catfish and loaches. Both FishBase and Seriously Fish recommend groups of five or more.
Stomach contents of wild fish are mainly aquatic and terrestrial insects and their larvae, with small amounts of algae and detritus. A good dried food as the staple plus frozen bloodworm, Daphnia and Artemia brings out the colour.
An egg scatterer with no parental care, and fry sometimes appear unaided in a mature planted tank. For a real yield use a dimly lit 20-30 litre spawning container over mesh the eggs can fall through, and remove the adults afterwards.
Hardy and tolerant of a wide range of water, so an easy beginner's fish. Males redden in the anal and caudal fins and are slimmer than females. Jumping is the main cause of loss, so never leave the lid open at feeding time. The IUCN rates it Least Concern and it is not listed by CITES.
Beginner. This is a beginner-friendly species. No special equipment or experience is required, and it can be kept successfully with basic care setup.
The ideal temperature for Pearl Danio is 16〜25℃. Avoid sudden temperature changes and maintain a stable environment.
The average lifespan of Pearl Danio is 3-5 years. With proper care and nutrition, they can live a long and healthy life.
Pearl Danio typically reaches Up to 9.6cm TL as an adult. Size may vary depending on care conditions and individual genetics.
Pearl Danio feeds on: Dried, frozen and live foods. Aim for a balanced diet with appropriate feeding frequency.
