To nitpick even further, "animes" would also be incorrect; the plural of animé is animé. Japanese nouns don't pluralise with "-s" endings.

But since this word has been pretty much incorporated into foreign languages, it's okay to use the plural endings like you normally would.
Just like when Japanese use English loanwords, they don't give a damn about using our plural s. Loanwords are bound to be changed a bit depending on the language imo.
