The Fire Goby, Fire Fish, Fire Dartfish, or Red Fire Goby is a marine dartfish. This fish is most commonly found near the substrate of the upper reef in tropical marine waters. These waters include the Indo-Pacific, Central Pacific, east African waters, Ryukyu Islands, Japan, New Caledonia, and Pitcairn Islands. They swim as deep below the surface as 70 meters, and usually hover directly above the ocean floor, facing the current to catch their prey. They eat mostly copepods, zooplankton, and crustacean larvae. They usually have a bright yellow head, merging into a white body, gradually shading into a red-orange tail. Their dorsal fins are very long, and the fish flicks it back and forth. This is used as a signal to conspecifics. As a full grown adult, it reaches a maximum length of 9 centimeters (3 in). Adults occupy sandy burrows alone or in pairs, while the juveniles live in small groups. These fish are monogamous. They will retreat to burrows if threatened.

The Ocellaris Clownfish, Common Clownfish or False Percula Clownfish (Amphiprion ocellaris) is a popular aquarium fish, even more so after it rose to stardom in Finding Nemo. It is very closely related to A. percula, the Orange Clownfish or “True Percula Clownfish”, and often lives in association with the sea anemone Heteractis magnifica, using them for shelter and protection. Generally, Ocellaris clownfish are hardier, and slightly less aggressive than its Percula counterpart. Both species are found in coral reefs of the Indo-Pacific, particularly in the Fiji and Tonga regions.
This clown anemonefish can be recognised by its orange colour with three white bars and black markings on the fins. It grows to about eight centimeters (three inches) in length. One can differentiate between Percula (true) and Ocellaris (false) by their respective colors and patterns. Ocellaris are usually less vibrantly colored, and have 11 dorsal fin-spines instead of 10, as on the Percula. There is also a rare melanistic variety hailing from the reefs around Darwin, Australia, that is a dark black colour with the normal white stripes. (text source: Wikipedia)
