No, they are not capable of learning (at least not my fish). The small tail wrasse I had jumped & I found it flopping around on the kitchen floor, but I scooped it back in. A month later, did the same thing. Found it behind the tank but took too long getting it out of there & it died two days later. Beautiful fish. Too bad it was a slow learner.
Ahhh, the joys of open top reef tanks
