"fishes" is the word used to refer to multiple species of fish. Unless the Oxford dictionary and Websters dictionary and every other English dictionary were all updated overnight.

For example, a perfectly correct usage would be "when you throw a bait in the sea...what do you expect the fishes to do?"

If you spent less time laughing at other people (even when you are wrong) and more time discussing blind Tunisian women you would be doing us all a huge favor.

Be careful when trying to mock others (especially on a thread about religion, no less!) in case it comes back to bite you and you end up looking foolish.
