do fish fart? if not, why don't they?

[mfj]

it seems they would, especially the fish that eat a lot of vegetation.

wow...a technical question...

I have NO idea. I'm going to go with no for arguements sake...but I have no reasoning to back it up.

 

[Cichlid-Man]

omg..........HAHAHAHAHAHAHAHA ok a way to see if its true is watch them....if bubbles rise then you got your answer.

I'd say no though just because.

Corys do, part of their 'breathing' is to swallow air (their semi-regular darts to the surface) which allows them to live in areas very low in oxygen. they then absorb the oxygen as it travels through their intestinal tract.

I can't say as I've seen any other fish fart tho

"True farting is a by-product of digestion, and some experts say that the digestive gases of fish are consolidated with their feces and expelled in gelatinous tubes (which fish then eat!). "

That is some great information! I need to get some corys so the next time i go to taco bell, I can blame it on the fish.

Any creature with a digestive system will have waste products in the form of gases...and yes all these creatures do have to expel these gases to remain healthy...some in the form of a "fart" and others in the form of a "burp"...If I remember correctly, fishes gills perform dual duty from taking in air and expelling "noxious" gases...

So to answer your question, NO fish do not fart but yes they do get "gas"...

How is that for a technical answer...*thumbsups

I'm sure fish fart . . . I had a school of 16 neons . . . the school always avoided one of them. They always seemed to stay "up current" from him. And upon further observation he always looked quite guilty.

Given the incontrovertible proof of Hawkeye's last two replies, I feel vindicated!!!
