Hoplias malabaricus, also known as the wolf fish, tiger fish, guabine or trahira, is a predatory Central and South American freshwater ray-finned fish of the characiform family Erythrinidae.
The maximum known length for this species is about 65 centimetres (26 in) and the maximum known weight is about 3.8 kilograms (8.4 lb). [4]
Like other members of the genus Hoplias this species has a cylindrical body shape with a large mouth equipped with prominent teeth. The dog-like teeth have given it some of its common names. Coloration is highly variable but is usually grey-brown with darker vertical stripes or a single horizontal stripe.
Southern Central America to Argentina. Found in most river systems and in the following countries; Argentina, Bolivia, Brazil, Colombia, Costa Rica, Ecuador, French Guiana, Guyana, Paraguay, Peru, Suriname, Trinidad and Tobago, Uruguay and Venezuela. [5]
Occurs in a wide range of freshwater habitats from clear, fast flowing, upland streams, to the slow turbid lowland waters, canals, irrigation and drainage ditches, and shallow, stagnant and hypoxic lakes and ponds. [6] They are adapted to Spends the daylight hours resting in vegetation and is most active during the night. Adults are ambush predators of fish (such as guppies), [7] crustaceans (such as shrimp and crayfish) and mussels; [7] while juveniles prey consists of crustacean and other invertebrate prey. This species spawns in pits located in shallow water and the males guard the nests even after the eggs have hatched.
Hoplias malabaricus are popular in the aquarium trade but are prohibited from being kept in California as a potentially invasive species. H. malabaricus was formerly established in Hillsborough County, Florida from either deliberate releases or fish farm escapes. Since January 1977 no specimens have been collected or reported; presumably the species was extirpated as result of extremely cold temperatures during that month. [8]
The Malabar danio is a tropical fish belonging to the minnow family (Cyprinidae). Originating in Sri Lanka and the west coast of India, the fish has been circulated throughout the world through the aquarium fish trade. It grows to a maximum length of 6 in (15 cm) but rarely exceeds 4 in (10 cm) in a home aquarium.
Polypterus senegalus, commonly known as the Senegal bichir, gray bichir or Cuvier's bichir, is an African species of ray-finned fish in the bichir family, Polypteridae. It is a typical example of polypterid fishes, as most of its defining physical features are common across the genus, such as its ancient, lungfish- or arowana-like appearance, the ability to breathe atmospheric oxygen, and its armor-like scales. These factors have influenced the species' popularity in captivity, and it is commonly kept by aquarists and other hobbyists.
The Erythrinidae are a family of fishes found in rivers and other freshwater habitats from Costa Rica south as far as Argentina. They are common and are caught with hooks by fishermen, partially because of their voracious behaviour. They are sometimes called trahiras or tarariras.
Upeneichthys lineatus, also known as the blue-striped mullet, blue-lined goatfish. blue-striped goatfish, blue-spotted goatfish and blue striped red mullet, is a species of marine ray-finned fish, a goatfish from the family Mullidae. It is native to the Pacific coast of Australia. It occurs in sheltered areas over rocky and sandy substrates and can be found 5 to 100 metres, though rarer below 40 metres (130 ft). This species can reach a length of 40 centimetres (16 in) FL. This species is commercially important.
The smalltail shark is a species of requiem shark, and part of the family Carcharhinidae. It is found in the western Atlantic Ocean, from the northern Gulf of Mexico to southern Brazil. It inhabits shallow waters close to shore, particularly over muddy bottoms around estuaries. It tends to swim low in the water column and forms large aggregations segregated by sex. A slim species generally not exceeding 1.1 m (3.6 ft) in length, the smalltail shark has a rather long, pointed snout, a broad, triangular first dorsal fin, and a second dorsal fin that originates over the midpoint of the anal fin base. It is plain gray in color, without prominent markings on its fins.
Hepsetus odoe, the African pike characin, is a predatory freshwater characin belonging to the family Hepsetidae. It was formerly considered that there was a single species of Hepsetus pike characin but recent studies have led to the species being split and Hepsetus odoesensu stricto is the west African representative of the group.
The striped Raphael catfish is a catfish of the family Doradidae. It may also be called Southern striped Raphael, talking catfish, chocolate doradid, chocolate catfish or thorny catfish. It is native to the Amazon, Paraguay–Paraná and lower Orinoco basins in South America. This peaceful, nocturnal species is a popular aquarium fish due to its pleasant temperament and curious nature. Despite its name "talking catfish", it does not speak.
The Spanish hogfish, Bodianus rufus, is a species of wrasse native to the western Atlantic Ocean, where it can be found from North Carolina and Bermuda through the Caribbean and the Gulf of Mexico to southern Brazil. It inhabits coral or rock reefs at depths of 1 to 70 m. While the adults feed on such prey as molluscs, crustaceans, echinoderms, worms, and small fish, the juveniles act as cleaner fishes. This species can reach a length of 40 cm (16 in), though most do not exceed 28 cm (11 in). This species is of minor importance to local commercial fisheries and can be found in the aquarium trade. When Marcus Elieser Bloch named the genus Bodianus he used Bodianus bodianus as the type species of the genus, this is a junior synonym of Bodianus rufus.
The Malabar trevally, also known as the Malabar jack, Malabar kingfish or nakedshield kingfish, is a species of large inshore marine fish of the jack family, Carangidae. It is distributed throughout the Indian and west Pacific Oceans from South Africa in the west to Japan and Australia in the east, inhabiting reefs and sandy bays on the continental shelf. The Malabar trevally is similar to many of the other species in the genus Carangoides, with the number of gill rakers and the grey-brown colour of the tongue being the diagnostic features. The Malabar trevally is a predator, taking a variety of small fish, cephalopods and crustaceans. The species is of minor economic importance throughout its range, caught by a variety of net and handline methods.
Serranus tigrinus, the harlequin bass, is a species of marine ray-finned fish, a sea bass from the subfamily Serraninae, which is a part of the family Serranidae, which also includes the groupers and the anthias. It can be found in the western Atlantic Ocean, and also in aquarium trades.
Echidna catenata, commonly known as the chain moray, is a moray eel found in shallow parts of the western Atlantic Ocean and from islands elsewhere in the Atlantic. It occasionally makes its way into the aquarium trade. It grows to a maximum length of 165 cm (65 in) but a more common length is about 40 cm (16 in).
