Types of Exotic Fish

Exotic fish are fish species that are rare, and most exotic marine life features unusual or unique markings, colors or characteristics. Exotic fish may be found in freshwater or saltwater, and a number of exotic fish are native to warm, tropical habitats.

Freshwater Species

A number of exotic fish species require a freshwater environment. These types of fish may be found in ponds, lakes, brooks, streams or rivers. Popular exotic fish in this category include the Malawi Blue Dolphin, Koi, the South American Leaffish, the Green Spotted Puffer, the Bala Shark and the Zebra Tilapia. Freshwater exotic species are sought after by fish enthusiasts because of the relatively inexpensive cost of maintaining a freshwater aquarium in comparison with saltwater aquariums.

Saltwater Species

Exotic saltwater fish need a salt water environment for survival. Fish in this category live in oceans, bays, gulfs, seas and lagoons. Prized saltwater fish species include the Porkypine Puffer, the Golden Sapo Puffer, the Bellus Angel Fish, the Percula Clownfish, the Achilles Tang Fish and the Rhinopius Scorpion Fish. Exotic saltwater fish may also be called marine fish or seawater fish.

Tropical Species

Tropical fish species, which may be found in saltwater or freshwater, have natural habitats with warm, tropical climates. Types of exotic tropical fish include Cichlids, New Guinea Rainbowfish, Labyrinthfish, the Fancy Plecostomus and the Payara. Tetra species, such as the Neon Tetra, the Congo Tetra and the Jewel Tetra, are classified as tropical fish as well.
