Pictorial Species Index - Body shape Pictures.
Sometimes you'll see a fish in a shop that you don't know the name of. Or the shop may not know and have received the fish under some fancy "trade" name. Quite often odd species come in mixed with other known species.
This index is arranged with pictures to hopefully allow you to home in on the species, or at least find one similar so that you can know what aquarium conditions will likely suit it.
If you click on the text next to the picture most similar in shape to the fish you wish to identify it will take you through a series of stages to hopefully find the correct Species Profile.
