Learned behaviour

[SeaHorse_Fanatic]

Learning from other fish in the tank is how I was able to teach my wild seahorses back in the "old days" before captive breds were common to eat frozen mysis. I always kept at least one wild seahorse who already knew how to eat frozen and he/she would teach the newcomers.

It does point to an inherent intelligence that they can learn. I know studies have been done with octopi, where one is trained to navigate a maze to get food, and then another is allowed to watch and will then get the maze right the first time its placed inside.
