There are many red ants, you might have to be more specific than that. Do you mean Myrmica rubra/Myrmica ruginodis?
These can have many queens, and are as far as I've heard fairly easy to keep and catch.

M yrmica rubra are cheap and easy to keep, but they sting, i trying to get one now, just preping some ytongs :D
