Looks like a black Claarki to me.
Definitely not a Saddleback or a black perc.
Clark's Clownfish - Amphiprion clarkii
The Clarkii Clownfish is also a highly popular aquarium species. They are sometimes sold under the name of "Sebae" clowns, which is actually the species name of a very different clownfish. Clarkii Clowns can reach a full grown size of about 4 inches, and can be territorial when full grown. This is a species easily cared for in aquariums and will accept a wide variety of foods. All clownfish eat some algae in nature, and this should be included in their diet.
Clarkii Clownfish are the most widely distributed anemonefish in the world, and show a large range of color variation. The color grown at ORA is the yellow-orange variety, which is the most popular, although in most areas the color is usually black with orange on the head and fins. They are one of the least picky species when it comes to host anemones, and will associate with Bubble-Tip, Long Tentacle and Carpet Anemones.
About one in 3,000 clarkii clowns born will show an interesting mutation in their eyes. A pearl white crescent appears in the upper part of the eye. ORA sells these fish as Pearl-eye Clarkii Clowns.
