"There is fish."

[anya_mz]

why "du" not "un"?

[Remy]

Because "Il y a UN poisson" means "There is A fish".

The sentence states fish, not a fish - please explain why is "poissons" is not an acceptable answer?

[LaurenG19]

I entered "il y a des poissons" and was marked correct. Maybe you used the wrong article?

Thank you, that must have been it :)
