Black Ocellaris Clownfish (Amphiprion ocellaris)

A black morph of the classic Ocellaris Clownfish, bred selectively over generations for that deep, almost velvet-black body rather than the usual orange, and it's proof of how much variation captive breeding programs have coaxed out of a single wild species. Every behavior that makes a regular Ocellaris such a staple of the hobby still applies here — same peaceful temperament, same tendency to host in an anemone or anything that resembles one, same total immunity to anemone stings thanks to the mucus coating on their skin. The only real difference is cosmetic, and it's a striking one; the coloring tends to develop and deepen further as the fish matures, so a young specimen may still be finding its final look.
