If you’ve followed the blog for a while, you’re probably aware of my disdain for extraneous, anthropogenic (man made) noises in aquariums. Such noises occur in the natural environments (boat motors, industrial machinery) of many cichlids. Eliminating such noises is unrealistic. Reducing them is not. I used to have a sister blog called The Bio Stage (it’s coming back, btw). In that blog, I often wrote about the effects of anthropogenic noise on cetaceans (e.g., dolphins and whales).
