Freshwater Sharks General description


Freshwater sharks are a group of freshwater fish belonging to the minnow family. While not a predatory species, freshwater sharks have long, powerful bodies and large dorsal fins, and are similar in physical appearance to marine sharks. Their vibrant colorations and fascinating behavior patterns make them favorites among most experienced aquarists.

Origins


Most species of freshwater sharks originate from different regions of Asia.


Color


Freshwater sharks come in red, silver, white, gold and black colorations.


Maintenance and care

One of the most important things to consider when buying freshwater sharks is their aquarium size. They are very active species and spend the majority of their time swimming along the lower regions of the aquarium. Most species also grow to over two feet in length and should only be kept in extremely large aquariums or ponds. Freshwater sharks also prefer aquariums which are heavily planted and have ample hiding spaces for them to retreat to when feeling threatened.


While not a predatory species of fish, freshwater sharks do sometimes show a tendency to chase and harass their tank mates. And although they not bite, their constant harassment can be extremely stressful and harmful for most timid species of fish. For this reason they should only be kept with larger, non-aggressive species of freshwater fish like cichlids or pacus. Freshwater sharks should not be kept with other bottom dwellers as they will often compete fiercely with them for territory and food. Some species of freshwater shark can also be extremely territorial towards members of their own species. Red tail sharks are an example of this and should only be kept in groups in an extremely large aquarium where each fish can mark out its own territory.


Feeding


Most freshwater sharks are omnivores and will readily accept most flake and pellet based foods. Their diet should also be supplemented with live foods such as brine shrimp and bloodworms.


They are very active species and spend the majority of their time swimming along the lower regions of the aquarium.


Breeding


It is virtually unheard of for freshwater sharks to breed in aquariums. Most specimens available for purchase today are bred in large fish farms in Asia.


Aquarium varieties


Bala Sharks, Redtailed Sharks, Columbian Sharks, Black Sharks, Rainbow Sharks, Silver Apollo Sharks, etc.
