"Die Fische sind nicht groß."

Translation: The fish are not big.

[HristiNi4]

there is a mistake in the English translation. Fish doesn't have a plural form. it should be always "the fish is / is not". not a problem if you are aeare of it but for English and German learners might be misleading.

if Die Fische' is plural why 'sind' and not 'seid'

"seid" is only used after "ihr".
