Common Clownfish [Amphiprion ocellaris]

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)

Clark’s Anemonefish

Clark’s anemonefish or the Yellowtail clownfish (Amphiprion clarkii) is a widely distributed clownfish. It is found in tropical waters, in lagoons and on outer reef slopes, from the Persian Gulf to Western Australia and throughout the Indian Ocean and Pacific Ocean as far as Melanesia and Micronesia, and as far north as Taiwan, southern Japan and the Ryukyu Islands.
Clark’s Anemonefish is a spectacularly colourful fish, with vivid black, white and yellow stripes, though the exact pattern shows considerable geographical variation. There are normally two white bands, one behind the eye and one above the anus. The tail fin may be white or yellow, but is always lighter than rest of the body.

Maroon Clownfish [Premnas biaculeatus]

The Maroon clownfish, the spine-cheeked clownfish, or the maroon anemonefish, Premnas biaculeatus, is a species of clownfish that is found in the Indo-Pacific from western Indonesia to Taiwan and the Great Barrier Reef.[1] They can grow up to be about 17 cm (6. 7 in), and as they grow, they become more aggressive towards other clownfish. It is the only member of the genus Premnas, although it has been suggested that the taxon epigrammata from Sumatra should be recognized as a distinct species, Premnas epigrammata (Fowler, 1904).

The stripes across the body are normally white, but they are yellow in the taxon epigrammata. The female is usually larger than the male and dark red or maroon, and the male smaller and a bright red.

Red Saddleback Clownfish [Amphiprion ephippium]

Red saddleback anemonefish or clownfish, Amphiprion ephippium, is a clownfish that lives in the Indo-Pacific area. They are considered small even for a clownfish, but are very aggressive toward other animals, especially to other types of clownfish. They don’t have the typical stripe. (text source: Wikipedia)

Orbicular batfish [Platax orbicularis]

The Orbicular Batfish (Platax orbicularis) is a popular aquarium fish endemic to tropical waters of the Indian and Pacific Oceans.

Its body is almost disc-shaped, and very thin; the tail, about 20% of the body length, is fan-shaped and taller than it is long. Males can grow to up to 50cm in length, though aquarium specimens are generally much shorter. In the wild, the Orbicular Batfish is found in brackish or marine waters, usually around reefs, at depths from 5 to 30 metres. Its range extends from the Red Sea and East Africa in the east to the Tuamotu Islands in French Polynesia in the west, and from southern Japan in the north to northern Australia and New Caledonia. It has been recorded off the coast of Florida, though this may be the result of dumping of aquarium specimens.

Juvenile fish are solitary or live in small groups, among mangroves or other inner sheltered lagoons. Adults are found in more open waters and at greater depth.

Wikipedia on batfishes: They are spade-shaped, laterally compressed, and very symmetrical triangular dorsal and anal fins. They are shiny silver with areas of yellow and vertical brown or black banding. The eyes are often located in one of the vertical bands as a method of camouflage. Scuba divers sometimes mistake them for angelfish, which are similar in shape but not closely related. Other genera in the family are characterized by long, trailing, pointed dorsal and anal fins.

Spadefish are generally considered to be an overfished group. Most of the individuals caught are small and young and are nowhere near the maximum size recorded for their species. A recent study in Current Biology (vol 16, p. 2434) has suggested that the batfish Platus pinnatus may play the role of a critical functional group in the Great Barrier Reef by eating seaweed that other herbivorous fish such as parrotfish and surgeonfish will not touch. Overgrowth of seaweed among corals occurs as a result of overfishing of large fish species and inhibits the ability of coral to support life.
