Interesting find... Also keep in mind that some bodies of water that are supposed to be "too cold" for some invasive species have things like power
plants or industrial plants adjacent. Guess where that waste heat goes and keeps the water at a balmy temperature well enough above freezing through
Fish may have a brain the size of a pea, but if cold is a problem for them they know enough to go where it's warm.
One or two fish aren't a problem. But there's still a risk of getting a breeding population where they don't belong.
