Phylum: Chordata
Class: Actinopterygii (ray-finned fishes)
Order: Perciformes (Perch-likes)
Family: Cichlidae (Cichlids)

Genus/species: Satanoperca leucosticta

GENERAL CHARACTERISTICS: S. leucosticta has a streamlined body shape which is greenish-yellow to yellow-brown color. The head area from the mouth to the back of the gill plates are covered in numerous small whitish or iridescent bluish spots, often with a reddish background.

 Length up to 15 cm (6 inches)

 

DISTRIBUTION/HABITAT: Found in South America: Essequibo River in Guyana and Nickerie River in Suriname.

DIET IN THE WILD: Eartheater name derived from this fish’s almost constant digging in the sand for prey (insects, crustaceans). It scoops up sand swallows the food and ejects waste out of its gills.

REPRODUCTION: Fish in this genus are mouth brooders. The parents take turns brooding and spit the fry into the partner’s mouth when their shift is over.

CONSERVATION: IUCN Redlist; Not Evaluated.

REMARKS: Genus name translates as “eartheater.” This common name applies to many species. A small, but popular food fish.

TAXONOMY
Kingdom: Animalia
Phylum:Chordata
Class: Actinopterygii (Ray-finned fishes)
Order: Characiformes (Characins)
Family: Anostomidae (Headstanders)

Genus/species: Leporinus fasciatus

GENERAL CHARACTERISTICS: The Black-Banded Leporinus has alternating colored bands of black and yellow. This striking pattern also suggests the age of a fish. Until about a year old, the juvenile has only five black bands, but about every six months later a band will split in two. At three years, the leporinus will have 10 bands, and the yellow will have a more orange cast. Females are larger than males.

Length up to 30 cm (12 in); 15 cm (6 in) is more common

DISTRIBUTION/HABITAT: Widely distributed in South America, from Guiana and the Orinoco region to the La Plata basin. Its natural habitat is rocky areas of fast-flowing streams and rivers, though it often migrates into flooded forest areas during the rainy season.

L.fasciatus has been introduced into the US states of Florida and Hawaii.

 

DIET IN THE WILD: Small invertebrates such as worms, insects, and crustaceans as well as other fish and plant matter. Like all members of its family, L. fasciatus very often positions itself had down (headstanders) to feed in rocky crevices or nibble on algae and green plants.

REPRODUCTION: The species is reported to build nests where the female lays eggs, which are guarded by the male. (fishbase)

MORTALITY and LONGEVITY: Life span: 5 years or more.

 

CONSERVATION: IUCN Redlist and CITES; Not Evaluated 

REMARKS: Leporinus (”rabbit”) relates to this fish’s two prominent front teeth The species is also known to leap out of the water, so perhaps its name has more than one reference point!

TAXONOMY
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii
Order: Characiformes
Family: Characidae (Characins)
Subfamily: Serrasalmidae

Genus/species: Piaractus brachypomus

GENERAL CHARACTERISTICS: Body is deep and laterally compressed, with silvery sides (becoming darker approaching the dorsum) and red coloration on the belly, chin, pectoral fins, and occasionally the leading rays of the anal fin. As in other characin species, a small, unrayed adipose fin is present approximately midway between the dorsal and caudal fins. The remaining rayed fins are uniformly dark-colored.

Length up to 88 cm (34.65 inches) Weight up to 25 kg (55.07 lb)

 

DISTRIBUTION/HABITAT: Tropical. South America: Amazon and Orinoco River basins in open water of large rivers and seasonally flooded forests. Pacu are a popular aquaculture species around the world.

DIET IN THE WILD: The dentition is comprised of 2 series of molariform incisors located on the premaxilla and 1 row of dentary teeth. The Red-bellied Pacu feeds on insects and decaying fruits and vegetation that fall in water.

REPRODUCTION: External fertilization. Although parents abandon their eggs, Pacu are brood hiders, minimizing the chances of the clutch being discovered by predators.

PREDATION: Humans and possibility Pirarucu (Arapaima gigas) and Black caiman (Melanosuchus niger).

Lifespan up to 25+ years.

CONSERVATION: IUCN Red list; Not evaluated CITES No special status

REMARKS: Because the Red-Bellied Pacu are closely related to Piranha, sharing their coloration and shape, Hollywood producers have been known to use the Pacu as a stand-in for piranha. Actors are appreciative of the Pacu’s preference for vegetable matter.

Pacu’s dentition allows them to crush fruit, nuts and seeds. Their teeth are cusped and resemble human molars, and they also have very powerful jaw. P. brachypomus can cause serious human bites of protruding anatomy.

Like the Tambaqui the Pirapitinga, is an important aquacultured food fish in South America.

All Pacu species are known for being able to adjust to unfavorable environmental conditions, such as depleted oxygen levels. Protrusion of the lower lip, all of which facilitate the use of surface water in respiration.

Phylum: Chordata

Order: Perciformes
Family: Cichlidae
Tribe: Lamprologini

Genus/species: Neolamprologus species

Male Neolamprologus brevis for example reach lengths of just 4.5 cm (1.75 inches) while females are even smaller, around 3 cm (1.25 inches) long. These cichlids probably evolved from fish that lived in rocky cave, but pressure from competition and the many predators of Lake

Lake Tanganyika has very high levels of carbonate hardness, and the calcium in the water ensures that empty shells dissolve much more slowly than they do in most rivers and lakes. In some places there are piles of shells more than 3 metres (10 feet) deep.

DIET IN THE WILD: Zooplankton and small invertebrates

REPRODUCTION: To protect their young eggs are laid by the female within a shell and fertilized as she lays them or immediately after by the male.The female protect the eggs within the shell by fanning her pectoral fins to keep the internal water oxygenated, and often rearranging the substrate to create barriers or to hide the shell from predators.

The eggs hatch within 48 hours, and the yolk sac is absorbed within five days. Fry typically emerge from the shell a week after spawning and they remain benthic for days or weeks after their emergence.
