Octopus

Octopuses are highly intelligent and curious marine invertebrates, capable of problem-solving and camouflage. Due to their large size, ability to escape, and specific care needs, octopuses are recommended for advanced aquarists. They require a secure, well-sealed tank with plenty of space and enrichment, such as live rock and puzzles. Their diet consists mainly of crustaceans and small fish, and they need stable water parameters to thrive.
