Clowns come in different colors and shapes and with tank Raised being more popular with them, you will soon discover there are two typical types - The True Percula: typically orange in color with three white bars, with the middle bar having a forward-projecting bulge. It has 10 (rarely 9) spines on the dorsal fin, while the False Percula has 11 (rarely 10) dorsal spines.
The False Percula, also called the Ocellaris Clownfish (Amphiprion ocellaris) is typically orange in color with three white bars, with the middle bar having a forward-projecting bulge. The False Percula has 11 (and rarely 10) dorsal spines as opposed to the True Percula which has 10 (rarely 9) dorsal spines.
If you compared the True Percula and the False Percula side by side, you would find that the spinous (anterior) part of the dorsal fin is taller on the False Percula than is the spinous part of the dorsal fin of the True Percula.
You appear to have one of each.
