Main Topic:
Sound is all around us including and especially underwater. Over 800 species of fish use sound to communicate, to help in finding food, in reproduction displays, and to show aggression, but some of those things are being dampened. The oceans have become an increasingly noisy place and all that sound is changing how fish and other ocean animals relate to their surroundings. There have been studies looking at the impacts of sound in the wild and even in freshwater ornamental species, but there has been limited work done on ornamental saltwater species. How does the equipment we use on our tanks and ambient noise from where they are located impact them?
