Given the question: Information:  - The Mekong giant catfish, "Pangasianodon gigas" (, ; /"try riec"/), is a very large, critically endangered species of catfish (order Siluriformes) in the shark catfish family (Pangasiidae), native to the Mekong basin in Southeast Asia and adjacent China. In Thai folklore, this fish is regarded with reverence, and special rituals are followed and offerings are made before fishing it.  - The Ariidae or ariid catfish are a family of catfish that mainly live in marine waters with many freshwater and brackish water species . They are found worldwide in tropical to warm temperate zones . The family includes about 143 species .  - Catfish (or catfishes; order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Named for their prominent barbels, which resemble a cat's whiskers, catfish range in size and behavior from the three largest species, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia and the Piraíba of South America, to detritivores (species that eat dead material on the bottom), and even to a tiny parasitic species commonly called the candiru, "Vandellia cirrhosa". There are armour-plated types and there are also naked types, neither having scales. Despite their name, not all catfish have prominent barbel. Members of the Siluriformes order are defined by features of the skull and swimbladder. Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food. Many of the smaller species, particularly the genus "Corydoras", are important in the aquarium hobby. Many catfish are nocturnal, but others (many "Auchenipteridae") are "crepuscular" or "diurnal" (most "Loricariidae or" "Callichthyidae" for example).  - Loricariidae is the largest family of catfish (order Siluriformes), with 92 genera and just over 680 species to date, with new species being described each year. Loricariids originate from freshwater habitats of Costa Rica, Panama, and tropical and subtropical South America. These fish are noted for the bony plates covering their bodies and their suckermouths. Several genera are sold as "plecos", notably the suckermouth catfish, "Hypostomus plecostomus", and are popular as aquarium fish.  - A fish is any member of a group of organisms that consist of all gill-bearing aquatic craniate animals that lack limbs with digits. They form a sister group to the tunicates, together forming the olfactores. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Tetrapods emerged within lobe-finned fishes, so cladistically they are fish as well. However, traditionally fish are rendered obsolete or paraphyletic by excluding the tetrapods (i.e., the amphibians, reptiles, birds and mammals which all descended from within the same ancestry). Because in this manner the term "fish" is defined negatively as a paraphyletic group, it is not considered a formal taxonomic grouping in systematic biology. The traditional term pisces (also ichthyes) is considered a typological, but not a phylogenetic classification.  - Candiru (English and Portuguese or "candirú" in Spanish), "Vandellia cirrhosa", also known as cañero, toothpick fish, or vampire fish, is a species of parasitic freshwater catfish in the family "Trichomycteridae" native to the Amazon Basin where it is found in the countries of Bolivia, Brazil, Colombia, Ecuador and Peru.  - The wels catfish (or ; "Silurus glanis"), also called sheatfish, is a large species of catfish native to wide areas of central, southern, and eastern Europe, in the basins of the Baltic, Black, and Caspian Seas. It has been introduced to Western Europe as a sport fish and is now found from the United Kingdom all the way east to Kazakhstan and China and south to Greece and Turkey. It is a scaleless freshwater fish recognizable by its broad, flat head and wide mouth. Wels catfish can live for at least fifty years and have very good hearing to compensate for their poor sight.  - Crepuscular animals are those that are active primarily during twilight (i.e., the period immediately after dawn and that immediately before dusk). It is thus to be distinguished from diurnal and nocturnal behavior where an animal is active during the hours of daylight or the hours of darkness respectively. The term is not precise, however, as some crepuscular animals may also be active on a moonlit night or during an overcast day. The term matutinal is used for animals that are only active before dawn, and vespertine for those only active after sunset.  - The domestic cat is a small, typically furry, carnivorous mammal. They are often called house cats when kept as indoor pets or simply cats when there is no need to distinguish them from other felids and felines. Cats are often valued by humans for companionship and for their ability to hunt vermin. There are more than 70 cat breeds, though different associations proclaim different numbers according to their standards.  - Corydoras is a genus of freshwater catfish in the family Callichthyidae and subfamily Corydoradinae. The species usually have more restricted areas of endemism than other callichthyids, but the area of distribution of the entire genus almost equals the area of distribution of the family, except for Panama where "Corydoras" is not present. "Corydoras" species are distributed in South America where found east of the Andes to the Atlantic coast, from Trinidad to the Río de la Plata drainage in northern Argentina. Species assigned to "Corydoras" display a broad diversity of body shapes and coloration. "Corydoras" are small fish, ranging from in SL.  - Callichthyidae is a family of catfishes (order Siluriformes), called armored catfishes due to the two rows of bony plates (or scutes) running down the length of their bodies. This family contains some of the most popular freshwater aquarium fish, such as the species of "Corydoras".  - Brackish water or briny water is water that has more salinity than fresh water, but not as much as seawater. It may result from mixing of seawater with fresh water, as in estuaries, or it may occur in brackish fossil aquifers. The word comes from the Middle Dutch root "brak". Certain human activities can produce brackish water, in particular civil engineering projects such as dikes and the flooding of coastal marshland to produce brackish water pools for freshwater prawn farming. Brackish water is also the primary waste product of the salinity gradient power process. Because brackish water is hostile to the growth of most terrestrial plant species, without appropriate management it is damaging to the environment (see article on shrimp farms).  - Detritivores, also known as detrivores, detritophages, detritus feeders, or detritus eaters, are heterotrophs that obtain nutrients by consuming detritus (decomposing plant and animal parts as well as feces). There are many kinds of invertebrates, vertebrates and plants that carry out coprophagy. By doing so, all these detritivores contribute to decomposition and the nutrient cycles. They should be distinguished from other decomposers, such as many species of bacteria, fungi and protists, which are unable to ingest discrete lumps of matter, but instead live by absorbing and metabolizing on a molecular scale (saprotrophic nutrition). However, the terms detritivore and decomposer are often used interchangeably.     Given the information above, choose from the list below the object entity that exhibits the relation 'parent taxon' with the subject 'ariidae'.
