do fish learn overtime ?

[Allmost]

Hello,
so we have all seen how our fish get used to us feeding, and follow us around as we walk around the tank.

some fish even learn about the timing of the fish feeders, and hang around there on feeding times.

anyone know if fish have the capability of pushing a lever to get food ?
many land animals do, they learn over time that standing on X means food drops down . but can fish do the same ?

Not sure about pushing a lever specifically, but there have been studies done on fish being able to remember mazes over a decently long time frame. I suspect that pushing a lever would be something they're capable of, but it'd be a difficult thing to train for I think.

Certain fish I think posses the potential of being trained to do something like press a lever or be trained do other simple action/reward behaviors.

I can see certain fish doing this, large wrasses seem great at problem solving.

There was an episode of myth busters about this.
