Nah, phylogenetically speaking, all descendants of fish must also be fish, by definition. Therefore, “being cold blooded” cannot also be a criterion (not that it would work anyway since tuna are warm blooded, BTW, and nobody would argue tuna aren’t fish).
The “living wholly in water” criterion actually works, though: land-fish (e.g. humans) live inside a bag of water that we carry with us.
They are kind of right … there is no such thing as a fish.
If I went down that rabbithole I think she would have punched me
Of course there’s such a thing as a fish! A fish is any swimming vertebrate (or its descendant), such as a tuna, or a duck, or a human.
Being cold blooded and living “wholly in water” are also requirements.

You believe in cladistics or you don’t, cowards!

Still an animal though
No such thing as birds.
Yes there are, they’re a kind of dinosaur
