Danio albolineatus
A pearlescent silver-pink schooler with iridescent flanks. Holds tighter shoals than zebra danios and is calmer at the surface. The right danio for nano communities where zebra danios are too rambunctious.
Pearl Danio (Danio albolineatus) reaches 5–6 cm as an adult and needs a minimum tank of 75 L. Native to Myanmar, Thailand, Sumatra, it lives in the mid to top water column with a peaceful (active) temperament. Aim for 20–26 °C, pH 6.0–7.5, and 2–15 dGH hardness. Lifespan is 5–7 years with good care. Keep pearl danio in groups of 8+, yes schoolers need numbers to display natural behaviour. Diet: omnivore, Flake, micro pellet, frozen daphnia and bloodworm. Plant-safe: Yes. Shrimp-safe: Yes (with adults).

Direct answers to the questions search engines and AI assistants surface most often about this species.
Pearl Danio (Danio albolineatus) needs a minimum tank of 75 L. They live in the mid to top water column and should be kept in groups of 8+, so a longer footprint matters more than depth.
Target 20–26 °C, pH 6.0–7.5, and 2–15 dGH hardness. Acclimate slowly when moving them between water sources.
Shrimp safety: Yes (with adults). Plant safety: Yes.
Pearl Danio are omnivore. Flake, micro pellet, frozen daphnia and bloodworm.
On Fin & Stem's 1–5 difficulty scale this species rates 1/5. Almost unkillable, a solid first-tank choice. Breeding difficulty: medium.
Typical lifespan in a well-maintained tank is 5–7 years.
A planted tank is a system. Pair this fish with one entry from each other pillar to plan the whole scape.
