Herring Break Wind to Communicate, Study Suggests
National Geographic: “Schools of herring communicate by passing gas, according to an unprecedented study. The fish apparently hear the bubbles as they’re expelled, helping them to find each other in the dark and form protective groups.”

The same must go for oscars. Its fine that they fart constantly under water, but don’t hold an oscar out of water for longer than 2 seconds. Its like a stink bomb mixed with even more pungent rotten fish guts.

Check out these beautiful pet oscars – there’s even a murderous one called Olivia.
