The black pearl killifish is an aggressive fish, and it is best to keep them alone. You can't keep a male and a female in the same tank because the male may chase the female who refuses to mate too much. They are sensitive to changes in water quality, so they need to keep the water stable when they are raised. On the whole, they still have some difficulties.
1. Water temperature: The black pearl killifish likes to live in the water environment with the temperature between 16 and 22 degrees Celsius. They can clearly perceive the change of water temperature, so when changing water, we should pay attention to controlling the temperature difference between new and old water, and do not let the water temperature difference before and after changing water be too large.
2. Water quality: They like to live in weak acidic soft water, but they are sensitive to changes in water quality. It is better to keep the water quality stable and not to replace it frequently. The pH value of the water is about 6.0 and the hardness is between 1 and 4 dH, which is the most suitable water environment for their growth.
3. Feeding: They are omnivorous fish. Insect larvae, insects, worms, crustaceans, flakes, etc., are acceptable to them. But when feeding, we should pay attention to timing and quantification, which is conducive to their health. In addition, it is better to choose a place for feeding to prevent food waste and to prevent food residues from damaging the water environment.
