Giant Danios (Devario malabaricus) are a species of Danio native to India and Sri Lanka.

Habitat

In the wild, Giant Danios inhabit fast flowing mountain streams with lots of rocks and dense plants along the banks.

They are a shoaling fish and are strong, fast swimmers. 

Male specimens of this species tend to be slimmer than Females when reaching maturity, with their striped pattern running across the tail. They become more colourful when ready to breed.

Females display more gold colours with steel blue spots, and tend to be rounder and more full bodied than the Males. Their striped pattern curves upwards at the base of their tail.

A comfortable temperature for these fish is between 18°C - 25°C.

Size

Our specimens currently measure approx. 4cm - 6cm

This species' maximum size typically reaches approx. 12cm

Aquarium

We recommend an aquarium with a minimum capacity of 150 Litres. These fish prefer a long tank in which to swim. If you house more than 10 individuals, more space will be required.

These are peaceful fish that do well in a community aquarium with other fish of similar size and temperament. They are fast swimmers and are always on the move.

Giant Danios thrive when in a group of at least 6 fish (10 is preferable) as they are a schooling fish, and more members of the shoal make them feeler safer and behave with more confidence.

The aquarium should have some plenty of plants around the periphery, and the substrate should be rocky, with lots of stones and pebbles. This will better replicate their natural environment.

These fish require the water to be well oxygenated. Regular water changes are required to keep the water fresh and clean, so special care and attention should be taken to ensure they have the correct conditions.

The tank should be well established to avoid any surprise changes in water parameters that may upset or be otherwise detrimental to the fish.

These fish are carnivorous - feed them with plenty of meaty or insect based food, such as daphnia, bloodworm, and mosquito larvae. They will also take a good quality flake food.

pH levels should fall between the 6 - 8 range.
Hardness should fall between 5 - 19 dGH

Behaviour

This fish gets along with most species of similar size. They can become very boisterous and excitable at feeding time, so it is best not to house them with slower fish, or those with long flowing fins.

This is a freshwater species - Do not put them in a marine / saltwater aquarium.
