The rainbow shark (Epalzeorhynchos frenatum) is a freshwater fish from Southeast Asia in the Cyprinidae family. The ruby shark is also known as the red-fin shark, red-finned shark, rainbow sharkminnow, green fringelip labeo, whitefin shark, and whitetail sharkminnow. Other names include fringeflip, greenfrill, greenlip labeo, redfish, redfin, redstriped shiner, and striped shiner.
Red sharks are members of the genus Carcharhinus, which includes other species such as blacktips, blues, whites, and requiers. There are currently three recognized species in this genus: C. albimarginatus, C. plumbeus, and C. rhombus. A fourth species, C. sorrah, was previously included within C. plumbeus but is now considered a junior synonym of C. rhombus. Scientists have suggested that some earlier specimens identified as C. plumbeus may actually be C. rhombus or another undescribed species; however, this claim has not been confirmed by further research.
C. albimarginatus can be found in the coastal waters of South Africa. It can grow to a maximum length of 120 cm (47 inches) and 0.9 kg (1.98 pounds). This species is an active predator that feeds primarily on invertebrates such as crabs, shrimp, and worms.
Labeo bicolor (also known as the redtail shark and redtail sharkminnow) is a freshwater fish in the Cyprinidae family of carps. It is unique to Thailand and is severely endangered, however it is prevalent in aquaria, where it is coveted for its deep black body and bright red or orange tail. The aquarium trade is significant to the species' survival.
Labeo bicolor originate in rivers draining into the Gulf of Thailand at low altitude, usually below 100 m (330 ft). Their range does not extend into the Andaman Sea because it is too deep for them to reach. However, some individuals may stray into these waters and be caught by fishermen there; they are then sold for food.
Labeo bicolor can grow to 70 cm (27 inches) long and weigh up to 2.5 kg (5.5 lbs). They have a circular body with a protruding jaw used for crushing crustaceans. The upper surface of the body is dark brown or black with white markings under the skin, while the underside is yellowish gray. There is also a large black spot on each side near the tip of the tail. The first two dorsal fins are similar in size, while the third one is much smaller. There are no teeth in the mouth except for three tiny papillae (nubs) on the floor of the mouth. No sexual dimorphism has been observed.
The Red Tail Shark (Epalzeorhynchos bicolor) is a tiny freshwater fish native to Thailand. It is also known as the Red Tail Black Shark, Fire Tail, Red Tailed Labeo, and Red Tail Shark Minnow. Despite its name, this fish is a species of carp, not a shark, and it belongs to the Cyprinidae family. It is usually found in large groups in rivers, canals, and ponds near waterfalls.
The name "shark" is used for many different types of fish that are not related by any evolutionary lineage to true sharks. Some of these useless names include: swordfish, manta ray, batfish, knifefish, hornfish, and sawfish. True sharks are classified into three main groups: cartilaginous fishes, bony fishes, and lobe-finned fishes such as frogs and newts. Fish like the Red-Tailed Shark are called actinopterygians. This means they have a dorsal fin on their back and gills that branch from the neck rather than from a separate head. There are other groups of fish that have similar features, such as sturgeons and paddlefishes, so they fall under the same category as the Red-Tailed Shark.
True sharks are responsible for some of the most amazing stories in science fiction books and movies. They appear in Jules Verne's 20,000 Leagues Under the Sea and in Disney's 10,000 Fists Beneath the Sea.

Here are some Red Tail Shark tankmates to consider:
Tampa Bay is home to several shark species, the most common of which are blacktip, bonnethead, great hammerhead, bull, lemon, nurse, and tiger sharks. Although rare, it is possible to see white sharks in Tampa Bay as well.
The presence of sharks in our waters should not be taken lightly. However, sharks are vital to the ecosystem because they keep prey populations low enough for other more powerful animals to survive. There have been no reported fatal attacks by any shark species in Florida or Tampa Bay specifically. However, if you encounter a shark you should try to stay calm and avoid making any sudden movements or sounds. If you are a swimmer, stay within swimming distance of shore or use a floatation device.
Sharks are commonly mistaken for other fish, such as tuna or marlin. If you come across a shark but can't identify it immediately, leave it alone and call a reputable wildlife organization such as Reef Check or Shark Spotters International instead of reporting it as a crime. They will be able to give you advice on how to correctly identify different species of sharks.
There are many ways that sharks influence humans. Shark skin, meat, and cartilage are all sold in markets around the world so they are important sources of income for local communities.
