Black cross fish are very irritable and aggressive, and are not suitable for mixing with other small fish, otherwise they will often bully other fish and eat the fins of other fish.They like to live in a relatively large space environment, so when raising, the water tank should be as large as possible.In addition, their eggs are sticky eggs, so more aquatic plants need to be planted in the water.All in all, the black cross is a highly viable fish, very easy to raise, suitable for novices to raise.
1. Water temperature: The water temperature suitable for the survival of black cross fish is about 22-26 ℃.During the breeding period, they have relatively strict requirements on water temperature, which needs to be controlled between 27-28 degrees Celsius.
2. Water quality: They like to live in soft water environment with weak acidity.The optimal pH value of the water body is between 6.8 and 7.0, and the optimal hardness of the water body is between 5 and 8.Water should be changed regularly to ensure good water quality.
3. Feeding: They are omnivorous fish, not picky eaters, but they have a big appetite.The feed can be selected from algae, nematodes, frozen blood worms, red worms and the like.Attention should be paid to feeding according to the number of feeding mantissa, feeding enough food.Otherwise, they are easy to attack other fish because of hunger.
4. Light: During breeding, the light needs to be kept soft, because their fertilized eggs have a high mortality rate under strong light.
