Information about Keeping and Caring for Danio Fish in Aquariums.
Giant danios are and will eat most any prepared or live aquarium fare, though the food does need to float at the surface. As with all danios, these fish are quite active and have high nutrient requirements, so select a flake food that will provide for their needs. In the wild, they pick off insects from the water surface, so they often won’t really chase after food that has left the surface until everything else is gone. These fish will do best when offered food several times a day, but offer what they can eat in 3 minutes or less at each feeding. If you feed only once per day, provide what they can eat in about 5 minutes.
Yesterday I adopted 3 fish. I adopted 1 Danio Fish and 2 Danio GloFish for my 3 gallon (11 litres) tank.
Since they are these fish will eat most any prepared or live aquarium fare, though the food does need to float at the surface. A balanced diet for them would include flake or pelleted foods, plant-based food, and occasional live prey.

Note the temperature of water in the aquarium. Danio fish usually spawn at temperatures in the low to mid 70s Fahrenheit. If it is much cooler or warmer than this it is unlikely that your danio is carrying roe.In case you are keeping your danio fish alone, then you can easily notice that it will try to hide in the shady areas, for the maximum of time. The timid fish can often leave eating because of stress and soon will die.Those aquarium hobbyists who possess a love for zebra danio because of their incredible beauty and physical brilliance may find it interesting that danio fish is the first vertebrates to be cloned.As these Zebra danios fish love to stay in schools, you need at least a 20-gallon fish tank to pet them. It will give them enough room to swim and play hard. Danios are not at all aggressive in nature so you can easily keep other tank mates who are similarly calm and polite.This development is so fast that after the hatching of the eggs, within 36 hours the fully developed larvae display food-seeking behavior. The generation time of an adult danio fish is 3 months. For more information on lifecycle, you can .Zebra Danio fishes are not picky about food. They literally eat anything they found, even their eggs. The best recommended zebra danio food is the floating flake food. Also, the frozen and dried blood worms or the mosquito larvae will be a great choice for zebra danio diet.When you are sure of the fact that the female danio fish is carrying eggs, it’s time to prepare another tank for them. Take a 10-gallon tank and set it adequately. A shallow bed of gravel is essential as when the females start spawning eggs, after 2 – 3 days, the eggs will settle at the bottom while passing through the cracks of the gravels.Giant Danios
Second only to the zebra danio in terms of availability and popularity are the giant danios in the genus Devario. Sandy to tan dorsally and ventrally, this species wears stunning silvery to golden splotches and broken lines atop swatches of cobalt blue along their flanks. Taking the common name from the fact that these species may exceed 6½ inches in length and attain a bulk that is easily several times that of a zebra danio, the giant danio is an active schooler that can add both color and activity to the community tank.
Requiring much larger environs than their zebra kin, the giant danios prefer long, deep aquaria that are outfitted with plenty of tall grasses and leafy plants (either artificial or living will suffice). Because of their large size and endlessly active movements, these fish can easily intimidate other, smaller species such as neon tetras, rasboras, and hatchetfish. Mix with hardy, schooling fish of similar size. Tiger barbs, red tailed sharks, and various catfishes mix well with giant danios, as do other danio species, as well as loaches, small freshwater eels, and other bottom dwellers that will keep out of the swimming range of the danios. Some cichlid keepers use these danios as target fish.
The variety that is my personal favorite is the black-spotted danio Danio nigrofasciatus. Also known as the spotted danio or the dwarf danio, this species wears a single to double stripe along its flank (like the zebra danio), but also has a single, double, or even a triple line of spots (or broken stripes if you prefer) along its lower flank. Particularly handsome specimens will also bear black speckles in their anal fins. Although they only grow to a demure 2 inches in length, these fish make up for what they lack in beauty with their size. Black-spotted danios also have, as do all their close relatives, a pair of thin, elongate barbels extending forward and downward from the corner of the mouth. Requiring slightly warmer waters than any other species of danio, these fish should be maintained at 80° to 82°F. Coming from some of the swampier environments to host any species of danio, these Burmese fish also fare better in tanks that are heavily outfitted with broad-leafed plants and driftwood snarls. As with all species of danio, house the black-spotted danio in schools of five to twelve (or more) individuals.
