Breeding Brachydanio albolineatus
The specie is spread in eastern India, Sumatra, where it lives in running waters. It`s a slender fish, with a prolonged body, medium flank oblate. In the superior part of the mouth it has 2 pairs of mustaches, the inferior one being longer. The anal fin is prolonged starting from the same place as the dorsal. It
can reach 5 cm length. The body color is blue to violet; the back is dark blue-grey with some shining scalds. The abdomen is light blue-silvery. It has a longitudinal line dark red to orange, with a blue-green hem. The anal fin is red-orange near the body and green-red on the opposite part. The female is less colored than the male.
They live in bench, being an active fish, that`s why they need large aquariums with a planted back area and space for swimming in the front part. The optimal temperature is 22-24° C, but in winter time it can also be 18-20° C. It eats almost anything from living food to dry food as flakes. For reproduction they need 10-15 liters aquariums. The position of the aquarium has to be as in the morning a ray of sun fall into the aquarium water. The chemistry of water is not important, but the water must be fresh. In the reproduction aquarium we`ll have to mount a nylon netting in order to protect the eggs. We`ll also have to plant some aquatic plants as: Nittela or Myriophyllum. The aquarium water must be filtrated and aerated for 3 days before adding the fish. In the evening we`ll add 4 females and 6 males which can spawn up to 600 eggs. The fry will hatch after 24-30 hours. In the first 3-4 days the fry are stick on the aquarium sides. After they start to swim free we`ll feed them with infusors or yolk of egg. If we use egg, this has to be given in small quantities not to alter the water. In aquarium you`ll also add a small filter with few bubbles because the fry is sensitive at water motion. The sexual difference is obvious: while males are slender and thin, the females are more voluminous (especially in the reproduction period).

To whom it may concern,
Thank you for sharing your knowledge and expertise on pearl danios. I have learned much valuable information from your website. I have some pearl danios coexisting happily with other community fish including guppies, blue danios, leopard danios, and one double tail male betta. They all seem to be doing fine together. My male betta, Doewy seems to keep out of the way of the rest of these fast moving fish. The pearl danios are truly a remarkable sight especially with their flashes of color as they swim with the other colorful fish. These are truly one of my favorite fish. For later reference, I have organized your website and other related websites that I may need later.
Sincerely,
Irene Steffen
