To breed fancy tail fish, such as guppies or bettas, start by setting up a separate breeding tank with clean, warm water and plenty of hiding spots. Introduce a male and female of the desired species, ensuring they are healthy and of breeding age. Once the female is ready, she will display signals of receptiveness, and spawning will occur. After spawning, remove the adults to protect the fry, and maintain optimal water conditions for the developing eggs and young fish.
They are aggressive at hatching and stay that way for their whole lives. They are VERY AGGRESSIVE when they are breeding.
Most fish consist of about 60-80% water, but this can vary depending on the species, age, and environment of the fish. Water is essential for various biological functions in fish, such as respiration, waste removal, and temperature regulation.
