How to raise the three-thorn lionfish:

1. Water temperature: The water temperature should be controlled at 22-28℃ to raise the three-thorn lionfish. Too low a temperature will reduce the appetite of the three-thorn lionfish and affect their normal growth.

2. Feeding: Three-thorn lionfish like active bait. When feeding, you can choose bait such as bloodworms and water worms. Live bait can provide more adequate protein for three-thorn lionfish.

3. Environment: Three-spined lionfish do not like places with light, so they need to be provided with a shady environment in the aquarium. A cave or driftwood can be placed at the bottom of the aquarium, where the three-thorn lionfish can rest and hide during the day.
