oops, that is the fish i was thinking of!! except i read max size is 51"Great Lakes said:Stickle. The African Tetra family has a genera called Hydrocynus. In this genera, you will find the African Tiger fish (Hydrocynus goliath) which attains a length of 5' (150 cm).
This is a tad longer than 51", so maybe mine is bigger than yours..
