Pearl danio care guide

Pearl danio tank size

Provide a tank base at least 90 cm long and 30 cm wide for this active species. The reported adult standard length for the pearl danio is 5.5 cm.Provide a tank base at least 35 in long and 12 in wide for this active species. The reported adult standard length for the pearl danio is 2.2 in.^[1]

Use a tightly fitted cover on the aquarium because these fish can jump through small gaps. Darker substrate and live plants suit the species, whereas sparse decoration may leave their colours paler.Use a tightly fitted cover on the aquarium because these fish can jump through small gaps.

Roots, branches and attached Microsorum, Bolbitis or Anubias can be used in the aquarium layout. Provide moderate flow, but avoid torrent-like conditions because small danionins use calmer margins in nature.Roots, branches and attached Microsorum, Bolbitis or Anubias can be used in the aquarium layout.

The species is reported from Myanmar, Indochina, Peninsular Malaysia and Sumatra in habitats ranging from streams to ponds and rice paddies. In these natural habitats, small danionins stay in calmer margins away from heavy torrents.The species is reported from Myanmar, Indochina, Peninsular Malaysia and Sumatra in habitats ranging from streams to ponds and rice paddies.

Pearl danio water parameters

Use water targets of 18–24 °C, pH 6.0–8.0 and 5–15 dGH, which fall within the species profile ranges.Use water targets of 64–75 °F, pH 6.0–8.0 and 5–15 dGH, which fall within the species profile ranges.^[1]

Test water weekly; ammonia and nitrite should be zero. Replace about one quarter of the water weekly using conditioned replacement water.Test water weekly; ammonia and nitrite should be zero. Replace about one quarter of the water weekly using conditioned replacement water.^[2]

Rinse filter media lightly in removed aquarium water during maintenance. Untreated tap disinfectants may harm bacteria living on the media.Rinse filter media lightly in removed aquarium water during maintenance. Untreated tap disinfectants may harm bacteria living on the media.^[2]

Feeding pearl danios

Feed pearl danios once a day, offering only what the fish consume within a few minutes. Uneaten food decomposes into waste, so avoid overfeeding.Feed pearl danios once a day, offering only what the fish consume within a few minutes. Uneaten food decomposes into waste, so avoid overfeeding.^[2]

Feed good-quality flake or granules as staple food. Supplement dried food with small live or frozen bloodworm, daphnia and Artemia.Feed good-quality flake or granules as staple food. Supplement dried food with small live or frozen bloodworm, daphnia and Artemia.^[1]

Pearl danio behaviour

Keep a group of at least eight pearl danios; eight to ten or more are recommended. Larger groups can make them less nervous in the aquarium.Keep a group of at least eight pearl danios; eight to ten or more are recommended. Larger groups can make them less nervous in the aquarium.^[1]

Pearl danios are described as very peaceful, but you should research companions and consider their small adult size.

Colours vary between localities: western Thai examples can have an orange upper body, while central Thai examples have blue there, and orange stripe shape varies too. Some traded fish may be hybrids with Brachydanio rosea.Colours vary between localities: western Thai examples can have an orange upper body, while central Thai examples have blue there, and orange stripe shape varies too.

Breeding pearl danios

Pearl danios scatter eggs and show no parental care. Some fry may appear in a mature densely planted aquarium without intervention.Pearl danios scatter eggs and show no parental care. Some fry may appear in a mature densely planted aquarium without intervention.^[1]

Adults eat eggs they find. A separate spawning setup with egg-protecting mesh or fine-leaved plants and later mature sponge filtration can increase fry yield.Adults eat eggs they find.

Pearl danio health problems

Ich is a protozoan infection that can cause salt-like spots, rubbing, reduced appetite and gill irritation. Microscopy confirms diagnosis. Quarantine new fish for 30 days and disinfect or separate equipment to reduce introduction risk.Ich is a protozoan infection that can cause salt-like spots, rubbing, reduced appetite and gill irritation.

Fin rot can cause fraying, red streaks and progressive fin loss. Poor conditions and stress encourage bacterial disease. Good water quality and addressing harassment reduce relevant risks; seek advice for worsening fins.Fin rot can cause fraying, red streaks and progressive fin loss.

Fungal infection may look like grey-white cotton on damaged skin. Injury and environmental stress impair protective mucus. Gentle handling and smooth furnishings reduce injury risk, while good water quality reduces environmental stress.Fungal infection may look like grey-white cotton on damaged skin.

Male or female?

Mature females tend to be rounder-bellied, slightly larger and less colourful than males. These differences stand out particularly when the fish are in spawning condition.Mature females tend to be rounder-bellied, slightly larger and less colourful than males.
