Painted Fish
Painted fish are ornamental aquarium fish which have been artificially coloured to appeal to consumers. This artificial colouring, also known as juicing, is achieved by a number of methods, such as Injection (medicine), injecting the fish with a hypodermic syringe containing bright fluorescent colour dye, dipping the fish into a dye solution, or feeding the fish dyed food. This controversial process is usually done to make the fish a brighter colour and more attractive to consumers. The colouring of the fish is not permanent, and usually fades away in six to nine months. This practice is distinct from the creation of genetically modified fish, whose colouring is passed on genetically and is permanent. Methods There are a number of methods for introducing artificial colour into fish. Dyes A common method of creating "painted fish" is through dye injection via syringe. Generally, fish are injected multiple times. Fish may also be dipped in a caustic solution to strip their outer F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Painted Indian Glassy Fish
Paint is a material or mixture that, when applied to a solid material and allowed to dry, adds a film-like layer. As art, this is used to create an image or images known as a painting. Paint can be made in many colors and types. Most paints are either oil-based or water-based, and each has distinct characteristics. Primitive forms of paint were used tens of thousands of years ago in cave paintings. Clean-up solvents are also different for water-based paint than oil-based paint. Water-based paints and oil-based paints will cure differently based on the outside ambient temperature of the object being painted (such as a house). History Paint was used in some of the earliest known human artworks. Some cave paintings drawn with red or yellow ochre, hematite, manganese oxide, and charcoal may have been made by early ''Homo sapiens'' as long as 40,000 years ago. Paint may be even older. In 2003 and 2004, South African archeologists reported finds in Blombos Cave of a 100,000-year-ol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lymphocystis
Lymphocystis is a common viral disease of freshwater and saltwater fish. The virus that causes this disease belongs to the genus '' Lymphocystivirus'' of the family Iridoviridae. Aquarists often come across this virus when their fish are stressed such as when put into a new environment and the virus is able to grow. The fish start growing small white pin-prick like growths on their fins or skin and this is often mistaken for infection by ''Ichthyophthirius multifiliis'' in the early stages. It soon clumps together to form a cauliflower-like growth on the skin, mouth, fins, and occasionally the gills. This virus appears to present itself as lesions at differing locations depending on the species of fish being attacked, often complicating initial diagnosis. Lesions at the base of the dorsal fin are common among freshwater species of Central American origin, most notably '' Herichthys carpintis''; inside the mouth of '' Herichthys cyanoguttatus'' and '' Geophagus steindachneri''; ...

Goldfish
The goldfish (''Carassius auratus'') is a freshwater fish in the family Cyprinidae of the order Cypriniformes. It is commonly kept as a pet in indoor aquariums, and is one of the most popular aquarium fish. Goldfish released into the wild have become an invasive pest in parts of North America and Australia. Native to China, the goldfish is a relatively small member of the carp family (which also includes the Prussian carp and the crucian carp). It was first selectively bred for color in imperial China more than 1,000 years ago, where several distinct breeds were developed. Goldfish breeds vary greatly in size, body shape, fin configuration, and coloration (various combinations of white, yellow, orange, red, brown, and black are known). History Various species of carp (collectively known as Asian carp) have been bred and reared as food fish for thousands of years in East Asia. Some of these normally gray or silver species have a tendency to produce red, oran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blood Parrot Cichlid
The Blood Parrot Cichlid (''Amphilophus citrinellus'' × ''Vieja melanurus''), or parrot cichlid, is a Hybrid (biology), hybrid species of fish in the family Cichlidae. The fish was first bred in Taiwan around 1986. Blood parrots should not be confused with other parrot cichlid (other), parrot cichlids or salt water parrotfish (family Scaridae). Natural colors of the fish are red, yellow, and grey: other colors are Painted fish, injected by breeders. Because this hybrid cichlid has various anatomy, anatomical deformity, deformities, controversy exists over the ethics of creating the blood parrot. One deformity is its mouth, which has only a narrow vertical opening. This makes blood parrots somewhat harder to feed and potentially vulnerable to malnutrition. The fish is known to be semi-aggressive. Despite its deformity, it can hold its own in a fight, and will prey on any small fish that can fit in its mouth.

Cichlid
Cichlids () are a large, diverse, and widespread family of percomorph fish in the family Cichlidae, order Cichliformes. At least 1,760 species have been scientifically described, making it one of the largest vertebrate families, with only the Cyprinidae being more speciose. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000. They are native to the Neotropics, Africa (including Madagascar), the Middle East, and the Indian subcontinent, although some species have been introduced worldwide. Many cichlids, particularly tilapia, are important food fishes, while others, such as the '' Cichla'' species, are valued game fish. The family also includes many popular freshwater aquarium fish kept by hobbyists, including the angelfish, oscars, and discus. Cichlids have the largest number of endangered species among vertebrate families, most in the haplochrom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oscar (fish)
The oscar (''Astronotus ocellatus'') is a species of fish from the cichlid family (biology), family known under a variety of common names, including tiger oscar, velvet cichlid, and marble cichlid. In tropical South America, where the species naturally resides, ''A. ocellatus'' specimens are often found for sale as a food fish in the local markets. The fish has been introduced to other areas, including India, China, Australia, and the United States. It is considered a popular aquarium fish in Europe and the U.S. Taxonomy The species was originally described by Louis Agassiz in 1831 as ''Lobotes ocellatus'', as he mistakenly believed the species was marine; later work assigned the species to the genus ''Astronotus''. The species also has a number of junior synonyms: ''Acara compressus'', ''Acara hyposticta'', ''Astronotus ocellatus zebra'', and ''Astronotus orbiculatus''. Description ''A. ocellatus'' examples have been reported to grow to about in length and in weight. The wil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Tetra
The black tetra (''Gymnocorymbus ternetzi''), also known as the black skirt tetra, petticoat tetra, high-fin black skirt tetra, black skirt tetra, black widow tetra and blackamoor, is a freshwater fish of the characin family (Characidae). It is native to the Paraguay River basin of south-central Brazil (mainly Pantanal region), Paraguay and northeast Argentina, but there are also populations in the upper Paraná and Paraíba do Sul Rivers that likely were introduced.Benine, R.C., Melo, B.F., Castro, R.M.C. & Oliveira, C.

Indian Glassy Fish
''Parambassis ranga'', commonly known as the Indian glassy fish, Indian glassy perch, or Indian X-ray fish, is a species of freshwater ray-finned fish in the Asiatic glassfish family Ambassidae. It is native to an area of South Asia from Pakistan to Vietnam, Malaysia and Bangladesh. The Indian glassy fish has an extraordinarily transparent body, revealing its bones and internal organs; the male develops a dark edge to the dorsal fin. The fish grows to a maximum overall length of . It occurs in standing water, especially in impoundments, and it breeds prolifically during the rainy season. The species feeds on crustaceans, annelid worms, and other invertebrates. It is, in turn, prey for larger fish, including snakeheads (family Channidae). The Indian glassy fish is not important as a food fish for humans, but is very common in the aquarium trade. Formerly classified as ''Chanda ranga,'' the species is also known as the Indian glassfish, Indian glass perch, and Siamese glassfish ...
