The expert replied to prepare the living environment: all marine fish live in the ocean. In order to cultivate marine fish, it is necessary to prepare special fish tanks and install heating rods, protein separators, hydrometers and aquarium lights.

Mixed seawater: prepare some seawater for them, and natural seawater is the most suitable. If not, sea salt can be used to prepare simulated seawater.

Choose feed: artificial feed is more suitable for feeding marine fish, but there are also some kinds of marine fish that need to be fed with live bait.

Precautions 1. Environmental stability: the environment of seawater is generally stable, so most marine fish are sensitive to environmental changes. But in artificial breeding, we should also pay attention to the stability of water temperature and quality to avoid discomfort.

2. Reasonable feeding: Although synthetic feed is more suitable for feeding marine fish, they also need nutrition, and breeders should regularly feed some live bait to ensure that they are nutritious.

3. Regular cleaning: The breeder should also clean the algae beside the fish tank regularly to prevent them from polluting the water quality and accelerating the deterioration of the water quality.
