Good point I have seen gold fish for sale in bait shops so in those places they know the gold fish will end up in a waterway.I wouldn't be inclined to think that's the problem... That doesn't stop goldfish from being a dime a dozen at every fish store in the US.
I would be very surprised if there was any legislation at all about these fish, I hadn't even heard of them until a couple weeks ago.
Maybe it also involves them having destructive potential? Weather Loaches will cheerfully live in any water temp and will just wreck fish nests come spring.
I found out about the best looking paradise fish after an internet search to figure out the beautiful fish a fish shop was using on their home page. Then I was irked that they didn't sell their mascot fish and never had.
