Hi..

I've heard about pretty North American minnows of 3-4"
maximum. Unfortunately I don't know their colloquial or
scientific names.

In a telephone call a friend told me about several other
pretty small North American Cold-water Fish.

Would like learn more about them.

Thanks in advance.


There are a lot of them. For an overview

There is an organization dedicated to them:

One that is frequently kept, but not so much in the US is:

Another is the least killifish

Many of the small carp relatives can be kept in aquariums, many known
as shiners

If you have a library than can get books, there is a book, "American
Aquarium Fishes" by Robert J Goldstein that discusses a great many
fish suitable for aquariums.
