What is the most optimal way to count the nucleotide bases of each fastq file in my directory using UNIX commands?

I have a bunch of fastq files, and I need to write a one line UNIX command that will write the word count (wc) of how many nucleotides EACH file contains, not the total. It should look like this:

321903 1.fastq

314156 2.fastq

13515 3.fastq

...

and so on.

So far I have

cat *.fastq | awk ‘NR%4 == 2 {print $0}’| tr -d ‘n’ | wc -c

but that doesn’t work. I can’t find the answer this specific anywhere.
