What is a baby angelfish?
Baby angelfish, or angel fish fry, are almost transparent when they are born, and this feature protects them from predators in the wild. Commonly found in the Amazon River and tropical freshwater habitats, this species is also quite popular among aquarium enthusiasts. The fry undergo a dramatic physical transformation before reaching adulthood. For the first few days, they have almost no swimming ability, so they remain in a fixed area and are greatly affected by environmental disturbances.
The development of a baby angelfish is extremely sensitive to water temperature and pH levels. A moderate water temperature of 26-28°C accelerates egg hatching and strengthens the fry's immune system. When ammonia levels in the water rise, the fry suddenly change color, which is considered an early warning sign.
