Natural habitat
Giant danios live in clear, shaded hill streams and small upland rivers with pebble or gravel beds, from India and Nepal east into Indochina. They school near the surface.
Where they are found
These fish originated from a diverse range of freshwater environments in India, Bangladesh, Myanmar, and Himalayan regions. They can be spotted in both temperate and tropical waters, exhibiting a wide tolerance to different aquatic conditions.
Aquarium care
For optimal care, maintain stable water parameters and ensure regular cleaning and filtration to prevent waste buildup. Water changes of 10-20% weekly are recommended to ensure a healthy environment. Provide ample swimming space, along with hiding spots and plants, to enhance their comfort and mimic their natural habitat.
Feeding
Feeds mainly on insects that fall onto the water, plus worms and small crustaceans. Offer good flakes and small pellets with regular live or frozen foods.
Compatibility
These fish are generally peaceful and do well in community tanks with other non-aggressive species. Avoid larger or aggressive fish that might pose a threat to the small, active Danios. They thrive in schools and prefer to be kept in groups of at least six for best behavior.
Breeding
An egg-scatterer with no parental care. Pairs spawn repeatedly, releasing small batches of eggs each time, and a female can lay more than 1,000 eggs. Use a separate tank with fine-leaved plants or a mesh base, and remove the adults after spawning.
