Discus fish

Discus fish or Symphysodon, colloquially known as discus, is a genus of cichlids native to the Amazon River basin. Due to their distinctive shape and bright colors, discus are popular as freshwater aquarium fish, and their aquaculture in several countries in Asia is a major industry. They are sometimes referred to as pompadour fish.Discus are fish from the genus Symphysodon, which currently includes the above species.However, another review of the genus published in August 2007 suggested that the genus held these three species: S. aequifasciatus (the green discus), S. haraldi (the blue/brown/common discus), and S. discus (the Heckel discus). Further arguments have been made that S. tarzoo was not described in accordance with ICZN rules and thus should be considered invalid and replaced with S. haraldi, currently considered a synonym of S. aequifasciatus by FishBase.

Blue Acara

The blue acara, Aequidens pulcher, is a very colorful freshwater fish in the cichlid family. This fish can be found in Central and South America, from Panama to Colombia. They can reach lengths of 20 centimetres (7.9 in). The name Aequidens pulcher is indicative to its looks; pulcher meaning "beautiful." The Blue Acara is a common cichlid sold in many pet stores and they are often confused with or sold as Green Terrors (Aequidens rivulatus). The body is stocky and compact with a steel blue-gray coloration. There are noticeable horizontal green lines on their faces and their blueish-green scales give them a sparkling appearance. They also have long flowing fins with a hint of orange to the tips.

Pterophyllum

Pterophyllum is a small genus of freshwater fish from the family Cichlidae known to most aquarists as "angelfish". All Pterophyllum species originate from the Amazon River, Orinoco River and Essequibo River basins in tropical South America. The three species of Pterophyllum are unusually shaped for cichlids being greatly laterally compressed, with round bodies and elongated triangular dorsal and anal fins. This body shape allows them to hide among roots and plants, often on a vertical surface. Naturally occurring angelfish are frequently striped longitudinally, colouration which provides additional camouflage. Angelfish are ambush predators and prey on small fish and macroinvertebrates. All Pterophyllum species form monogamous pairs. Eggs are generally laid on a submerged log or a flattened leaf. As is the case for other cichlids, brood care is highly developed.

Asiatic glassfish

The Asiatic glassfish are a family, Ambassidae, of freshwater and marine fishes in the order Perciformes. The species in the family are native to the waters of Asia and Oceania and the Indian and western Pacific Oceans. The family includes eight genera and about 50 species.The family was formerly known as the Chandidae, a name which ITIS continues to use. FishBase notes that Ambassidae, which were named by Klunzinger in 1870, has priority over Chandidae, which was created by Fowler in 1905.The Ambassidae reach a maximum size of about 26 cm (10 in). Many of the species are noted for their transparent or semi-transparent bodies.A number of species are used as aquarium fish, noted for their transparent bodies. The Indian glassy fish, Parambassis ranga, is sometimes injected with coloured dyes by dealers in Thailand. The process, known as painting, dyeing, or juicing fish, is strongly opposed by many in the aquarium community. UK-based aquarium publication Practical Fishkeeping has been campaigning since 1997 to stop the trade in these fish, and runs a global register of stores which have pledged not to stock them. More than half of the UK's aquarium shops have signed up and the fish are now less common in the UK as a result.

Clownfish

Clownfish or anemonefish are fishes from the subfamily Amphiprioninae in the family Pomacentridae. Thirty species are recognized, one in the genus Premnas, while the remaining are in the genus Amphiprion. In the wild they all form symbiotic mutualisms with sea anemones. Depending on species, Clownfish are overall yellow, orange, or a reddish or blackish color, and many show white bars or patches. The largest can reach a length of 18 centimetres (7.1 in), while the smallest barely can reach 10 centimetres (3.9 in).Clownfish are native to warmer waters of the Indian and Pacific oceans, including the Great Barrier Reef and the Red Sea. While most species have restricted distributions, others are widespread. Clownfish live at the bottom of shallow seas in sheltered reefs or in shallow lagoons. There are no clownfish in the Atlantic.
