Common name: Pearl Danio
Scientific name: Danio albolineatus
Family: Cyprinidae
Origin: Burma, Sumatra, Thailand
Adult size: 6 cm / 2.5 inches
Tank Specs
Minimum Tank Size: 20 gallons, spawning 10 gallons
Water Parameters (PH/GH/KH): pH (6.8-7.2), medium-hard water, 2 to 6 dH
Temperature: 72-80 °F (22-27°C)
Special Requirements: Pearl Danios are not specific about water conditions providing extremes are avoided. The Pearl
Danio is a VERY active/energetic shoaling species that should be kept in groups. They accept most setups but prefer to
have a few fine-leafed plants on which to spawn. Make sure your aquarium has a tight-fitting lid, as they are enthusiastic
jumpers. Place plants along the back and sides with plenty of room in the middle of the tank so that they may swim freely.Suitable Tankmates: should be kept with other small lively fishes, of peaceful community temperament
Minimum Group Size: 5 or 6
Diet: They will accept all types of food when kept in an aquarium. They are omnivores (both plant and animal foods) and they will eat just about any of the standard aquarium fare that is offered. A varied diet is best. Veggies, flakes, microworms, algae wafers, tubifex, bloodworms, seaweed, etc.
Sexing: Males are slimmer and more intense in their coloration than females; females tend to show a rounder belly full of eggs.
Breeding and Reproduction: Egg-scattering species.
Breeding: Pearl Danios can be spawned both in couples and in schools. Provide your Pearl Danio breeding tank with Java moss or other suitable plants, or a layer of marbles on the bottom so the fish can scatter their eggs where they can’t reach and eat them. The water should only be 3 or 4 inches deep, a current is helpful (this species spawns in streams in the wild) and the addition of airstones will contribute to aeration. Separate males from females and condition with high quality foods for two weeks. Introduce males & females, spawning should occur within 1 or 2 days. Spawning requires temperatures of up to 78 degrees F, and can be trigged by raising the water a couple of degrees near dawn, when spawning normally occurs. 300 to 500 eggs will be scattered across the bottom and on the plants. Remove parents from the breeding environment after successful spawning, as they will eat their eggs.
Fry Care: Fry should hatch in 24-40 hours. Feed the fry infusoria and newly hatched brine shrimp for the first week. After about a week, they should be large enough to accept finely powdered fry food and other dietary sources (powdered egg yolk may also be added to the fry food to promote growth).
Notes: Make sure the aquarium is covered, as the fish can be so active that they leap from the water. Also, Danios are known for gobbling up food quickly, so tankmates should be bold & fast species capable of taking their fair share.
