How to raise black devils for beginners:

1. Water temperature: Black devils have requirements for the water temperature for survival. Generally, it is enough to keep the temperature between 23-27 ℃, which can keep the black devil active. When raising black devil juveniles, the temperature should be controlled between 26-28 ℃, which can improve the survival probability of black devil juveniles. When feeding, the temperature difference between day and night water temperature should not be greater than 4 ℃.

2. Water quality: Black devils are very sensitive to water quality. The pH suitable for the survival of the black devil is 6.5-7.2, and the hardness is 4-12. Black Devils can be farmed using tap water. But be careful, put the tap water in the sun to dry for a period of time before use to remove the chlorine.

3. Feeding: Black Devils prefer animal bait. During feeding, live bait feeds such as water earthworms, red worms and brine shrimp can be fed. Some artificial feeds can be additionally fed to supplement nutrition. When the black devil is in the breeding period, try to choose frozen red worms and frozen brine shrimp for feeding, so as to avoid the threat to the health of the black devil caused by the bacteria carried by the live bait.
