the blue devil fish? The blue devil fish looks very beautiful, but no one can imagine that they are a very fierce ornamental fish. This kind of fish is particularly aggressive, and they are very harmful to some small ornamental fish. If the breeder insists on mixing the fish with other fish, it is recommended to choose some ferocious fish larger than them for mixing.
This kind of fish has a high demand for water quality. It is recommended to change half of the water in the aquarium in 5-7 days when raising at home. The water should be thoroughly changed every half month. In this process, it is necessary to strictly control the difference in water quality and temperature between new and old water. It is precisely because there are some difficulties in the regulation of water quality that this kind of fish is not so simple to raise.
1, water quality: They have higher life activity in seawater. When raising blue devil fish, the acidity and alkalinity of the water should be adjusted to a weak alkaline state between 8.0 and 8.5. Regularly clean the water body to ensure the clarity of the water quality in order to better maintain their health. When there is a problem with the water quality, they will have a reduced desire to eat, slow activity and other phenomena.
2. Feeding: When feeding this fish, choosing artificial feed is the most conservative and safest method. In order to ensure their healthy growth, they can be supplemented with protein regularly. At this time, you can choose some frozen baits such as tubificidae and shrimp.
3. Aquarium: They need to live in an environment with enough space. The aquarium should be at least 150 liters to meet their living needs. When the space is too narrow, they will also be very irritable.
