Dracula fish Dracula fish The dracula fish ("Danionella dracula") is a species of tropical danionin fish from the cyprinid family. It is a freshwater fish endemic to Myanmar. A close relative is "Brachydanio rerio", the zebrafish of aquariums. It is named dracula after its unusual "fangs"; male dracula fish have protruding tooth-like bones stemming from their jawbones. Males have been observed using their fangs to spar with other males. Identified in April 2007 from specimens shipped to the United Kingdom in a consignment of aquarium fishes, the dracula fish has so far only been found in the wild in a small stream
Tropical fish divers keep lists of fish species they have observed while diving, especially in tropical marine environments. Coral reefs occupy less than 1% of the surface area of the world oceans, yet they provide a home for 25% of all marine fish species. Reef habitats are a sharp contrast to the open water habitats that make up the other 99% of the world's oceans. However, loss and degradation of coral reef habitat, increasing pollution, and overfishing including the use of destructive fishing practices, are threatening the survival of the coral reefs and the associated reef fish.
