They do best in slightly acid, or neutral water, with a pH ranging from six to eight. They also prefer elongated tanks. They are an omnivorous fish, their diet can consist of the usual fish foods: live blood worms, glass worms, brine shrimp, tubifex worms, as well as frozen vegetables, daphnia, mosquito larvae, brine shrimp, and plankton. The Great Danio will also eat flake and freeze dried foods. The Giant Danio is known as a jumper, so it is very important to cover your tank with a tight fitting lid. Breeding The Giant Danio is not difficult to breed in captivity. The breeding tank should be long with bushy plants covering the bottom. The purpose of the plants is to prevent the parents from eating the eggs. The Great Danios are egg scatterers. A typical spawn will consist of roughly 300 eggs. It is generally recommended that the parents be removed after eggs are laid. The eggs will hatch in about 30 hours. The fry are easy to raise.
Habitat Fresh water fish - Their habitat should be decorated moderately with live plants, driftwood, and rocks. Behavior The Giant Diano, or Danio aequipinnatus, is a great community fish. It will actively school with other fish of the same size. They also are known for their ability to jump, so they should be kept in a covered aquarium, or they might jump out. They are especially useful for cycling new aquariums, as they will do well in water with high levels of nitrate and ammonia nitrate. There are several long-finned varieties, which are very beautiful as well. Being such an extremely active fish, the Great Danio is known to unnerve other, more docile fish. They become powerful jumpers when they mature, which can make for an interesting show. Great Danios should be kept in schools, as they are a social fish. They are not overly aggressive. Three to five Danios can be kept in a minimum of 10 gallons. Be warned, however, the Great Danio might nip on live plants.
