Reminds me of a hillstream loach, maybe a goby ?
Heiko is still a pretty agile person at 65 years of age
I met him at the Canadian Association of Aquarium Clubs convention in London Ontario in May 2009.
He has an incredible knowledge of fish and their biotopes, has published many books and he has introduced many fish to the hobby
