Collection: Danio

Danios are schooling fish in the Family Cyprinidae. Most species grow to less than 2” and are typically surface oriented. A few types, like dangila and giant danios can reach 5” in length. They are incredibly hardy and tolerate a wide range of temperature and water chemistry, making them excellent fish for beginners and newly set up aquariums. They are active, to the point of being boisterous, but rarely cause injury to other fish. A number of color variants and long-finned versions have been developed through selective breeding. White cloud mountain minnows are included in the danio group as they are closely related fish that come from the same region and have the same aquarium needs.

Danios are native to south and Southeast Asia. Habitat varies from fast flowing streams to quiet pools. In recent years a number of new species have been discovered in remote areas of Myanmar (Burma) and have been introduced into the hobby.

Most danios tolerate a wide range of water chemistry and temperature, making them ideal beginner fish. pH should be between 7.0 and 7.8, alkalinity between 3° and 8° dkH (50 ppm to 140 ppm), and temperature between 70° and 78° F.

Danios are always on the go and should be kept with other active fish. Good tankmates include serpae, red eye and black skirt tetras, platies, mollies and swordtails, small barbs and other danios.

Long tanks with ample swimming room are best. Strong current from the filter or additional circulation pumps helps replicate their riverine habitat. Most danios are surface oriented, so having tall plants or ones that float at the top help make them feel at home. They will be less stressed and show their best colors in a well decorated aquarium. Danios are best kept in schools of at least 6 or more. Keep a secure lid on the aquarium to prevent them from jumping out.
