Its 9gag, most of the people use english as a secondary language. That means no rules
Do you say "there are many fish in the ocean" or "many fishes in the ocean".
Biologically, there is no such thing as a fish. Most aquatic animals are closer in DNA profile to land animals, than whatever is swimming next to them.
yeah, same with fruit/fruits, what's your point?
How about multiples of the same species by referring to the species name? 2 sharks, 2 goldfishes? Or does it remain 2 goldfish? And 2 shark?
Is it the same rule in English and American?
I think the 2. Is called a school?
What if each species have more than 1 fish... so it is called fisheses?
