English: All five currently recognized species of Hydrocynus compared. I recognize that this isn't the best quality image, but unfortunately my photography skills and my involvement in the aquarium community didn't develop at the same time. In spite of the quality of some of the images that I've had to use here, I feel that this image is unique and could potentially contribute to the site.

The fish pictured are as follow (top photo to bottom): Hydrocynus vittatus, Hydrocynus tanzaniae, Hydrocynus forskahlii, Hydrocynus brevis, and Hydrocynus goliath.

All fish pictured here were between five and six inches (13-15 cm) in length.
