The fish you are describing is likely a stonefish. Stonefish are known for their ability to camouflage by resembling rocks or algae in their environment. They are extremely venomous and can be found in coastal waters of the Indo-Pacific region.
Stonefish do not hibernate. They are typically found in tropical waters and are active year-round. They camouflage themselves among rocks and coral, using their venomous spines to ambush prey.

Simply to provide camouflage. A stonefish gave up the ability to swim fast long ago in the evolutionary chain in favor of a strong venom (injected by spines in the dorsal fin) and the appearance of a stone on the ocean floor. That is why a stonefish has a lumpy body, and is grey, mostly featureless, and best left alone. Answered by PHYSICSguru
Stonefish have 13 spines on their back that inject a toxin when pressure is placed on them, such as a larger fish attacking or a human stepping on them. They have evolved a stone like camouflage that aids in hunting. They lie in wait for a smaller fish to swim by and suck it in at lightning speed.
Stonefish are carnivorous and primarily feed on small fish, crustaceans, and mollusks. They have a sit-and-wait hunting strategy, using their excellent camouflage to ambush unsuspecting prey that swim by. Once within striking range, stonefish use their lightning-fast reflexes and venomous spines to incapacitate their prey.
Depending on the type, about 20 or 30 years.
