Rasbora – Galaxy, Celestial Pearl Danio CPD’s – 1cm

Celestial Pearl Danio (CPD) – A Shimmering Nano Tank FavouriteThe Celestial Pearl Danio (Danio margaritatus), also known as Galaxy Rasbora or CPD, is a stunning freshwater species admired for its iridescent, pearl-like spotting and elegant red-orange fins. Native to Southeast Asia, these small, peaceful fish thrive in planted aquariums and add both colour and movement to community nano tanks. Their ease of care and vibrant beauty make them a favourite among aquarists of all experience levels.Size and LifespanCPDs typically grow to just 2–2.5 cm in length, making them ideal for compact tanks. Despite their small size, they can live up to 5 years when maintained in stable, clean environments with a balanced diet.Ideal Tank SetupA well-planted tank of at least 20 litres is ideal for a group of CPDs. Use dark, soft substrates and provide dense vegetation such as mosses, ferns, and small-leaved plants to replicate their natural habitat. Gentle filtration and subdued lighting help showcase their colours and reduce stress. Maintain water parameters at a pH of 6.5–7.5 and temperatures between 22–26°C.Compatible Tank MatesCelestial Pearl Danios are peaceful schooling fish that should be kept in groups of six or more. They coexist well with:Ember TetrasPygmy CorydorasCherry ShrimpSparkling GouramisAvoid housing them with large or aggressive species, which can cause stress or injury.Feeding and NutritionThese omnivores do best on a varied diet of micro-pellets, high-quality flakes, and occasional live or frozen treats such as baby brine shrimp or daphnia. Feed small portions twice a day to match their natural feeding behaviour and prevent waste build-up.Breeding and BehaviourCPDs are relatively easy to breed. Males become more intensely coloured during courtship. A separate breeding tank with fine-leaved plants or moss will encourage spawning. Once eggs are laid, adults should be removed to prevent them from eating the eggs. Fry will hatch within 2–3 days and should be fed infusoria or powdered fry food initially.In groups, CPDs display confident schooling behaviour and darting movements. Their peaceful nature makes them ideal for calm community aquariums.Species OverviewSpecies: Danio margaritatusCommon Name: Celestial Pearl Danio, CPD, Galaxy RasboraOrigin: Southeast AsiaDiet: OmnivorouspH Range: 6.5–7.5Temperature: 22–26°CCurrent Size: 1 cmMax Size: 2–2.5 cmMinimum Tank Size: 20 litresBehaviour: Peaceful, schoolingBreeding Type: Egg-layerFAQs about CPD’sHow many CPDs should be kept together?
