The breeding cycle of black Mary fish is about 4-6 weeks. If the breeding environment is suitable for reproduction, they can reproduce every four weeks. If the reproduction is slightly worse, the reproduction cycle will be longer. If the environmental conditions are poor, they may not be able to reproduce.
Generally speaking, the black Mary fish growing in a suitable environment will have the ability to reproduce after about five months of growth. Some precocious individuals may be able to reproduce in about four months. However, in the actual culture, it is more recommended to select individuals with growth time of more than 6-8 months as parent fish for reproduction. In this way, more high-quality fry can be produced.
3 What environment is suitable for black Mary fish to breed1. Water temperature: The water temperature range suitable for black Mary fish to breed is 25-28 ℃. Higher water temperature is more conducive to the growth of juvenile fish. If the water temperature is very low, their reproductive cycle will become longer.
2. Water plants: Black Mary fish are more suitable for breeding in water tanks with water plants. Because aquatic plants can provide shelter and help newborn fish avoid risks.
3. Water quality: When breeding black Mary fish, moderate hardness and weak alkaline water should be used. This kind of water is more suitable for the growth of young fish.
