Danio

• Zebrafish (Danio rerio): This species has blue and yellow stripes along its sides, and is widely used in scientific research, especially in genetics and developmental biology.
  Zebrafish can regenerate their fins, heart, and brain after injury, and have many genes that are similar to humans.

• Blue Danio (Danio kerri): This species has turquoise blue scales with red or gold lines, and is also known as the turquoise danio or Kerr's danio.
  It is a peaceful and social fish that prefers planted tanks with moderate water flow.

• Pearl Danio (Danio albolineatus): This species has silver, pink, or white scales with thin black stripes, and is also known as the pearl danio or spotted danio.
  It is a lively and colorful fish that can tolerate a wide range of water conditions.
  Females have fleshy barbels on their lower jaws, while males have longer fins.

• Glowlight Danio (Danio choprae): This species has bright orange or red scales with blue or purple spots, and is also known as the fire danio or choprae danio.
  Glowllight Danio is a rare and beautiful fish that needs soft and acidic water, and plenty of hiding places.

Danio is a genus of small freshwater fish that belong to the family Cyprinidae.
There are 27 species of Danio, and they have different habitats and distributions.
Most Danio species live in calm or stagnant water, such as ponds, rice paddies, canals, and ditches.
Some species prefer fast-flowing streams and rivers.
Danio fish are native to South and Southeast Asia, and they can be found in countries such as India, Nepal, Bangladesh, Myanmar, Thailand, Malaysia, and Sumatra.

One of the most popular species of Danio is the zebrafish, which has thin horizontal stripes along its body.
Zebrafish are widely used in scientific research, especially in the study of genetics and development.
Zebrafish can also be kept as pets in home aquariums, along with other colorful species of Danio, such as the blue danio, the pearl danio, and the glowlight danio.
These fish are usually peaceful and active, and they like to swim in schools.
They need a well-planted tank with clean water and a moderate temperature.

Danio fish are omnivorous, which means they eat both plant and animal matter.
In the wild, they feed on algae, insects, worms, crustaceans, and other small organisms.
In captivity, they can be fed with flakes, pellets, live, or frozen foods.
Danio fish are also easy to breed, and they usually spawn in the morning.
The females lay eggs among the plants, and the males fertilize them.
The eggs hatch in about two days, and the fry are free-swimming in about four days.

Danio fish are interesting and attractive animals that have adapted to various habitats and conditions.
They are also valuable for scientific and recreational purposes.
Danio fish are an example of the diversity and beauty of nature.
