We do not routinely use feeder fish, but the few times that we have had too when weaning a fussy preditor, we've used guppies, tetras or small goldfish because the most commonly used feeder fish, rosey red minnows (Pimephales promelas), are simply never (or very rarely) available in the uk.
I'd often wondered why this is until today, while researching something else I discovered that you have to hold a licence to keep them!
It's because they are non-native fish that could easily survive in our native waters and out-compete our local fish.
Although the licences are issued free-of-charge, the law would require and fish store selling these minnows to see the buyers licence before selling them the fish.
Anyone found in possesion of the fish without a licence could be fined up to £2500.
We live and learn.
