It’s best to include a variety of plants in your tank setup, both rooted and floating. While they need space to swim, having places to hide among live plants is more important for celestial pearl danios – especially when they are kept in groups. ![]() Tank Décorīecause these fish are naturally found in ponds throughout the mountainous region of Myanmar, they prefer a richly planted tank. A slow bubbling sponge filter is the best option for filtration, though heavily planted tanks may need a small power head filter to promote water circulation. While these fish can withstand fluctuations in water chemistry, they require high water quality. The ideal tank parameters for celestial pearl danios are: There’s no need to worry too much about the specific values but be sure to conduct large frequent water changes to keep the water quality in the tank high. The natural water parameters in which these fish are found are neutral pH or slightly above 7 with medium hardness. Tank parameters appear to be unimportant for this species as long as they are kept relatively stable. The more densely planted the tank, the better. If you plan to keep multiple males in one tank, it’s important to provide enough space for weaker males to escape. Male celestial pearl danios will spend most of their time sparring with rival males and courting females. These fish will exhibit some shoaling behavior, but they don’t tend to school in the traditional sense. A group of six individuals will do perfectly well in a tank as small as 10 gallons. Tank size is less important for celestial pearl danios than tank setup. They aren’t a true shoaling species either, so they don’t need to be kept with large numbers of their own kind to thrive. These fish aren’t particularly active swimmers, so they don’t need a great deal of space. The celestial pearl danio appears to be a rather undemanding fish in terms of tank parameters as long as its base requirements are met. A mature female can be identified by the black anal spot that separates the reddish base of the anal fin from the yellow-white belly color. Their flanks brighten and darken while their belly turns red, causing their pearly spots to stand out. Male celestial pearl danios will display color changes during courtship and breeding. The bodies of both sexes are sprinkled with pearly white or light-yellow dots and the belly in females is yellowish white. The fins of male fishes are more brightly colored as well, and the caudal peduncle is higher than a female’s. Males of the species are typically bright blue in color compared to a dull blue-green background seen in females. In fact, the celestial pearl danio most resembles the emerald dwarf danio ( Danio erythromicron), another small cyprinid native to Inle Lake in Myanmar.Ĭelestial pearl danios exhibit some degree of sexual dimorphism. Their bodies are a little less elongated than pearl danios ( Danio albolineatus). These fish typically grow no longer than 1 inch (2-2.5cm) in length and their bodies are about three times as long as they are high. Like all danios, the celestial pearl danio is a small cyprinid – a member of the carp or minnow family. This little fish made a splash in the aquarium industry when they were first discovered in 2006 and they have been popular among hobbyists ever since. The celestial pearl danio – also known as the galaxy rasbora – is a small species native to Myanmar and northern Thailand where they can be found in freshwater ponds surrounded by grassland and rice paddies. With their dark blue bodies covered in bright white or yellow spots, these little fish are aptly named. Native Distribution: Myanmar, northern Thailand.Common Names: celestial pearl danio, galaxy rasbora. ![]()
