One way this phenomenon has been studied is on the basis of the repeated stress model done by Camp RM et al.(among others). In this particular study, it was examined that the contribution fear conditioning may play a huge role in altering an animal's (Fischer rat's) behavior in a repeated stress paradigm.
Fish fulfill several criteria proposed as indicating that non-human animals experience pain.

Most fish have sensitive receptors that form the lateral line system, which detects gentle currents and vibrations, and senses the motion of nearby fish and prey. [1] Sharks can sense frequencies in the range of 25 to 50 Hz through their lateral line. [2]
A further series of experiments showed that, similar to humans, under conditions of long-term intense psychological stress, around one third of dogs do not develop learned helplessness or long-term depression. [71] [72] Instead these animals somehow managed to find a way to handle the unpleasant situation in spite of their past experience.
