Gautama Buddha was not a vegetarian yet now  Buddhists monks are vegetarians.
Shd be Gautama Buddha told them not to eat meat and fish in his last teachings before he uplorry.

He did say it and it's in the sutras. Go and read the Lankavatara sutra. I extract a small part of it here:

"The Buddha told Mahamati, “There are countless reasons why you should not eat meat. But I will summarize them for you.
Because all beings have at some time been reborn as family members, out of your feelings for them, you shouldn’t eat meat."
