I think this is the case throughout the hobby. Where ever you're from I bet there's a good number of natives right in your back yard that are totally overlooked. But people seem to want what's on the other side of the world rather than set up a native tank.
Here in the uk, and being a fisherman, I know exactly what's on offer, from the humble stickleback to the monster pike, and they're all coldwater fish, no messing around with heaters and all the potential aggro that can come with them.
I have a plan one day to set up a European perch tank. It's probably a long way down the line but yeah, a native set up is certainly on my bucket list.
The stickleback is an amazing fish!!
