Nocturnal hunting

Unlike many other marine aquarium fish, lionfish are nocturnal, especially at dusk and dawn. They swim slowly, silently, then suddenly dart out, spreading their pectoral fins to form a "shield" to corner their prey, and they even use their tongues as bait to lure small fish.

Defense with poisonous thorns

Lionfish have many sharp spines containing venom on their dorsal, pectoral and pelvic fins. When attacked or threatened, they will fluff their fins, turn around and raise their sharp spines to "warn" the enemy. They almost only use their sharp spines for self-defense and rarely use them to actively attack other fish.

Fast and strong reproduction rate

Lionfish can reproduce all year round in the natural environment, each time they spawn they can lay from 15,000 to 30,000 eggs, and the total in 1 year can be up to 2 million eggs. After being laid, the eggs will float freely in the seawater and spread everywhere by ocean currents.
