Over a single spawning period the female can produce up to 700 eggs. Females will breed with several different males, and vice versa. The best sites contain a gravel bottom with a variety of plants. When the breeding season arrives, males choose suitable spawning locations and guard them from other males.
Dominant animals have access to the best food and breeding territories. Their schools have dominance hierarchies that the fish develop by chasing and biting one another. In the wild and in home aquariums, these creatures live in groups known as schools.
Behavior of the Zebrafishįor such a small and insignificant-looking fish, this species has relatively complex behavior. Finally, you can feed these fish commercially prepared fish food. This species also thrives in habitats with a variety of real or artificial vegetation for them to hide in. They do not require extensive space, but the more fish you keep in the tank, the tank you need to purchase. These fish thrive in small schools of the same species or other danios. Additionally, you should always buy animals bred in captivity and not captured from the wild. However, you should always do your research before purchasing a new pet so that you fully understand their care requirements. This fish makes a great pet for home aquariums. Humans have not fully domesticated this species. However, despite these interactions, their population numbers are quite high and the IUCN lists the species as Least Concern. Additionally, damming of waterways impacts wild populations. In their wild range, people also capture this fish to sell in the pet trade. People frequently own these little fish as pets in home aquariums. Humans interact with these fish quite frequently, both directly and indirectly. Some common prey items include small insects, insect larvae and eggs, zooplankton, algae, and more. They feed by snatching up floating particles and small invertebrates in the water column. Because most measure just an inch long, their prey must be quite small. These fish are omnivorous, which means that they feed on both plants and animals.
