Jack Dempsey Fish aka Nandopsis Octofasciatum Fish aka

Source: From Wikipedia, the free encyclopedia

The Jack Dempsey (Nandopsis octofasciatum) is a cichlid fish named for the 1920s boxer Jack Dempsey. The name alludes to its aggressive nature. Like most cichlids it is territorial, especially against its own kind and similar species. The fish was once very popular due to its striking appearance and personable mannerisms. While it is a popular aquarium fish, due to its behavior it is not easy to keep.

The coloration changes as the fish matures from a light gray or tan with faint turquoise flecks to a dark purple-gray with very bright, iridescent blue, green, and gold flecks. The dorsal and anal fins of mature males have long, pointed tips. Females lack these exaggerated tips.

The fish is native to Yucatan and Central America, where it is found in slow-moving waters, such as swampy areas with warm, murky water, weedy, mud- and sand-bottomed canals, drainage ditches, and rivers. It is also established as an introduced species in Australia, the USA and Thailand (presumably as an aquarium escape). The Jack Dempsey natively lives in a tropical climate and prefers water with a 7–0 pH, a water hardness of 9–20 dGH, and a temperature range of 72–86 °F (22–30 °C). It can reach up to 25 cm (10 in) in length. It is carnivorous, eating worms, crustaceans, insects and other fish.

Jack Dempseys lay their eggs on the substrate (the bottom of the aquarium or pool). Like most cichlids, they show substantial parental care: both parents help incubate the eggs and guard the fry when they hatch. Jack Dempseys are known to be attentive parents, pre-chewing food to feed to their offspring.

In 1997 the San Francisco Chronicle reported that a man had died when he put a Jack Dempsey into his mouth as a joke: the fish presumably erected its fin spines to avoid being swallowed, a characteristic cichlid anti-predator response, and became wedged in the man’s throat.

Goldfish aka Carassius Auratus Fish aka

The Goldfish (Carassius auratus) was one of the earliest fish to be domesticated, and is still one of the most commonly kept aquarium fish. A relatively small member of the carp family (which also includes the koi carp and the crucian carp), the goldfish is a domesticated version of a dark-gray/olive/brown carp native to east Asia (first domesticated in China[citation needed]) that was introduced to Europe in the late 17th century. The mutation that gave rise to the goldfish is also known from other cyprinid species, such as common carp and tench.

Goldfish may grow to a maximum length of 23 inches (59 cm) and a maximum weight of 9.9 pounds (4.5 kg), although this is rare; most individual goldfish grow to under half this size. In optimal conditions, goldfish may live more than 20 years (the world record is 49 years); however, most household goldfish generally only live six to eight years. [1]

Goby Fish aka Microgobius Gulosus Fish aka

The gobies form the family Gobiidae, which is one of the largest families of fish, with more than 2,000 species in more than 200 genera.[1] Most are relatively small, typically less than 10 cm (4 in) in length. Gobies include some of the smallest vertebrates in the world, like species of the genera Trimmaton and Pandaka, which are under 1 cm (3/8 in) long when fully grown. There are some large gobies, such as some species of the genera Gobioides or Periophthalmodon, that can reach over 30 cm (1 ft) in length, but that is exceptional. Although few are important as food for humans, they are of great significance as prey species for commercially important fish like cod, haddock, sea bass, and flatfish. Several gobies are also of interest as aquarium fish, such as the bumblebee gobies of the genus Brachygobius.

The most distinctive aspect of goby morphology are the fused pelvic fins that form a disc-shaped sucker. This sucker is functionally analogous to the dorsal fin sucker possessed by the remoras or the pelvic fin sucker of the lumpsuckers, but is anatomically distinct: these similarities are the product of convergent evolution. Gobies can often be seen using the sucker to adhere to rocks and corals, and in aquaria they will happily stick to glass walls of the tank as well.

Gobies are primarily fish of shallow marine habitats including tide pools, coral reefs, and seagrass meadows; they are also very numerous in brackish water and estuarine habitats including the lower reaches of rivers, mangrove swamps, and salt marshes. A small number of gobies (unknown exactly, but in the low hundreds) are also fully adapted to freshwater environments. These include the Asian river gobies (Rhinogobius spp.), the Australian desert goby (Chlamydogobius eremius), and the European freshwater goby Padogobius bonelli.

Glowlight Tetra Fish aka Hemigrammus erythrozonus aka Redglow Fish aka

The Glowlight Tetra is a small tropical fish that is found in the wild in Essequibo River Guyana South America. It is silver in colour and an bright iridescent orange to red stripe extends from the snout to the base of its tail. The front part of the dorsal fins are the same color as the stripe. Other fins are silver to transparent. Glowlight tetras are peaceful and schooling fish. It is slightly larger than the neon tetra, and its peaceful disposition makes it an ideal, and popular community tank fish. They should be kept with similar sized and non-aggressive species.

They are a medium size tetra growing to upto 4cm (max. 5cm), notably larger than both Neon Tetra’s and Cardinal Tetra’s. They have a life span of 2 – 4 years when kept in good conditions.

Glowlight’s are Omnivore, they eat small live, frozen and dry foods. The feeding of vegetable matter is suggested to vary the diet of the Glowlight Tetra.

Glo lights, Glo-light tetras, Glolight are alternative names. H. gracilus is old scientific name. Red-line Rasbora ( Rasbora pauciperforata) of Malaysia and Indonesia are different species with similar coloring. Glowlight Tetras are readily available and are usually very inexpensive. There is a golden Glowlight Tetra and albino Glowlight variety being offered for sale too.

Discus Fish aka

Source: From Wikipedia, the free encyclopedia

Discus are freshwater perciform fish, peculiar cichlids native to the Amazon River basin. There are two recognized species, both within the genus Symphysodon: the red discus or common discus (Symphysodon discus) and the blue discus (Symphysodon aequifasciatus). The two species are very similar and may interbreed, producing a number of hybrid strains. Details regarding the precise number of subspecies have not been finalised. Discus are most closely related to the genus Heros.

The first special characteristic of the discus is its flattened body shape. It is compressed from the sides to a dish or discus shape. Although patternation varies, most are showily coloured in shades of green, red, brown, and blue. The height and length of the grown fish are both about 20–25 cm (8–10 in).

The second special characteristic of the discus is its care for the larvae. Like all cichlids, the parents care for the young but the discus has a unique way of doing so: the parents produce a secretion through their skin, off which the larvae live during their first few days. The young can be seen grazing off their parents.

The discus are shy and peaceful aquarium inhabitants. They are sensitive to stress and disturbance or lack of protection. The best cohabitants may be angelfish (although many aquarists claim that keeping them together with angelfish will introduce parasites and/or diseases in them) and small characides like tetras. The Uaru is another preferred tank-mate of the discus. However, small fish may be intimidated by the big discus fish or even eaten. Small chacarins like neon tetras are often found in the gut of wild discus, so they might not be the ideal cohabitants, but the ideal food.

Also suction mouth ancistras (plecos) prove less than ideal for discus since they often attach themselves on the sides of discus and eat their mucus membranes.

The popularity of the discus has given it its nickname among aquarists: “the King of the aquarium.”

Catfish aka Channel Catfish aka

Catfish (order Siluriformes) are a diverse group of fish. Named for their prominent “barbels”, which give the image of cat-like whiskers, they are found in primarily freshwater environments of all kinds, with species on every continent except Antarctica. Some species from the families Ariidae and Plotosidae are also found in marine environments. They feature some of the smallest known vertebrates, including the candiru, the only vertebrate parasite to attack humans, as well as Pangasianodon gigas, the largest reported freshwater fish. There are armour plated types and also naked types, but they do not have scales. Not all catfish families have barbels; what defines a fish as being in the Siluriformes order are certain features of the skull and swimbladder.

Botia Fish aka Clown Loach Fish aka

Source: From Wikipedia, the free encyclopedia

Botia is a genus of freshwater fish in the Loach family (Cobitidae). It was a large genus with about 20 species. In 2004 Maurice Kottelat proposed in his paper (along with the description of Botia kubotai, see References below) to divide the genus into four related genera based on the fish appearance and locality:

Botia for Indian loaches (shorter body).
Chromobotia for Clown loach.
Parabotias are quite like the tiger loaches, mostly chinese.
Syncrossus for tiger loaches (elongated body).
Yasuhikotakia for Mekong loaches (shorter body).

The fish in these genera possesses a pair of spines under the eye sockets. They are normally hidden but may be extracted when the loach feels threathened. This behavior is infrequently observed. However, care has to be taken when catching it using fishnet as the extracted spines may get entangled to the nets causing injury. One special capability of these loach group is the ability to produce loud “clicking” noise. It is commonly heard during feeding time. Many loach individuals prefer to sleep on their side or other strange positions.

The most well known fish of the group is the Clown Loach (Chromobotia macracanthus), which is often kept by aquarists.

Source: From Wikipedia, the free encyclopedia (Redirected from Betta fish)

The Siamese fighting fish (Betta splendens) is one of the most popular species of freshwater aquarium fish. It is a member of the gourami family (family Osphronemidae) of order Perciformes, but was formerly classified among the Anabantidae. It is native to the Mekong basin in Southeast Asia.

The natural colouration of B. splendens is a dull green and brown, and the fins of wild specimens are relatively short; brilliantly-coloured and longer-finned varieties have, however, been developed by breeders (see Appearance, below.)

As B. splendens is the Betta species most commonly known to aquarium hobbyists, it is often but imprecisely sold as, and referred to, simply as “betta” (as a common name), particularly in the United States. The name “betta” can, however, also refer to any of the nearly fifty other members of the genus, including the type species, the spotted betta (B. picta). The fish is known as pla-kad in its native Thailand.
