Can fish hear and if so how is there hearing compared to ours? I just got my tank up and running and the 2 maxi 900's, Mag 7 in the sump, and mag 5 running the ugj makes some noise. Will they be alright? will it shorten there lives?
I cannot begine to give you a comparison to human hearing, but fish hear well enough, and actually communicate with sounds quite often. (clicking, grunting noises) They cannot however hear airborne sounds.
