Who does not love the gudgeon (Gonk) one of the very first fish i caught as a youngster. Very similar to barbel in how they behave, from feeding but also rolling/flash but only having two barbels. We have filmed them trying to take small minnows and the young are nearly transparent. The gudgeon truly is a stunning and most beautiful fish. #freshwaterfish #nature #gudgeon #underwaterphotography #rivers #scubadiving #environment | Beneath British Waters
