Celestial Pearl Danio

The Celestial Pearl Danio (Danio margaritatus), commonly known as the CPD or Galaxy Rasbora, is a small and beautifully patterned freshwater fish known for its dark body, pearl-like spots and bright red-orange fins. Peaceful and colourful, they are especially well suited to mature planted aquariums with plenty of cover.

• Adult size: Approximately 2–2.5 cm

• Temperament: Peaceful but can be shy

• Social behaviour: Shoaling species and should be kept in groups of at least 6–8, with groups of 10 or more preferred

• Tank mates: Best with other small peaceful fish such as tiny rasboras, Green Neon Tetras, Pygmy Corydoras, Otocinclus and peaceful shrimp

• Avoid with: Large, aggressive or highly active fish that may intimidate or outcompete them for food

• Recommended temperature: 20–26°C

• Recommended pH: Approximately 6.5–7.5

• Water hardness: Soft to moderately hard

• Minimum tank size: Around 30–40 L for a small group, with larger tanks preferred for bigger shoals

• Tank setup: Best kept in a mature, heavily planted aquarium with mosses, fine-leaved plants, shaded areas and gentle filtration

• Diet: Omnivorous; feed fine flakes or micro pellets alongside small frozen or live foods such as baby brine shrimp, daphnia and cyclops

• Care level: Beginner to intermediate

• Swimming level: Primarily lower to mid-water

CPDs are social shoaling fish rather than tight-schooling fish. They often spread out through the aquarium when comfortable, with males displaying and sparring around plants. Keeping them in a larger group helps reduce shyness and encourages more natural behaviour and colouration.
