What is a breeder tank?

A breeder tank is an aquarium designed for fish breeding. It is usually smaller in size and provides a controlled environment for breeding fish. The tank typically has a filtration system, heater, and lighting to simulate day and night cycles. The breeder tank is often divided into two or more compartments, allowing male and female fish to be separated until pairing or spawning occurs. The tank may also have breeding cones or spawning mops, which can act as a substrate for the fish to lay their eggs on. Breeder tanks are commonly used by fish hobbyists to ensure the successful breeding of their fish species.
