Onyx (Amphiprion percula) 

Description:
Onyx are a percula variant that exhibit more than normal black coloration. The black color comes from the black margin that usually outlines the white bars, however, in this case the black color has begun to spread out and cover the normal orange color of the fish. The amount of black on the body must be more the 50% of the orange skin to make it an onyx. If it is less than 50% it is called a Semi-Onyx.

Behavior:

Like all clownfish, Amphiprion percula is a sequential hermaphrodite. The largest individual present will exert dominance and become reproductively female. The next largest fish will become reproductively male. The female may not tolerate other smaller individuals.

Compatibility:
Usually ignores reef invertebrates and corals. Clownfish sometimes adopt various corals and algae as substitutes for host anemones.

Food:
Proaquatix specimens have been weaned to take aquarium pellets and flakes. Freshly frozen invertebrates such as ocean plankton, Mysis shrimp, brine shrimp, and chopped squid.
