What kind of sensory adaptations would be beneficial to the cave fish to allow it to navigate life in a cave, including catching and eating food?

Although the cave fish have non functional eyes, it can see in the darkness of the cave and it catch their prey by contracting their mouth, thereby producing suctions that trap its preys. Thus, the cave fish expanded other sensory organs to make up for their sight less eyes. Also, cave fish, can only hear lower frequencies noises. The noise in the cave is always above this, thus the cave fish has developed the auditory adaptation of filtering out background noises in its environment.
