Danio albolineatus is a widely available species that is a great addition to most community aquariums. Thespecies is commonly called the pearl danio ,which refers to the pearl-like sheen of the body. Healthy, in-condition specimens often demonstrate a variety of beautiful color schemes. The majority of specimens sport an iridescent purple or pink body, a yellow or neon-orange stripe running roughly 1/3 or more of the body length to the caudal fin, yellow or neon-orange eyes, hints of olive on the body, and subtle hints of yellow in the fins.
D. albolineatus is a highly underrated and often overlooked fish by many hobbyists, as it may not appear to be an eye-catching species in a local fish shop due to being housed in brightly lit living quarters with little or no structure. In addition, D. albolineatus typically carries a small price tag, so hobbyists often assume that it will maintain the same dull colors once they get it home. Luckily, there are a few easy things that hobbyists can do to bring out the true beauty of this community aquarium mainstay.
