Discus Fish

Discus fish are a great choice if you are looking for an exotic fish which is easy to care for. These fish are brightly colored and are circular in shape (and they look like discs). They are very popular due to their coloring and intricate patterns. Some of the most popular types are the red, blue and turquoise Discus. These fish can grow up to 8-10 inches, says William S. White Winnetka. Others love the Discus because they have been known to recognize their owners or others who approach their tank.



Axolotls are growing rapidly in popularity. Originally from Mexico City, they are also known as the Mexican Salamander. They have cartoonish features and are often described as ‘adorable’. They are classified as amphibians. Axolotls require at least an 11-gallon tank, and their water must be changed frequently. They should be kept on smooth and fine sand as well.


Flowerhorn Cichlid

The flowerhorn cichlid is originally from Malaysia, and they are known for their beautiful colors and their large size. These fish are often combinations of red, blue, pink, yellow and orange and have flowerlike markings on their bodies. Flowerhorn Cichlid do not like to live with other fish and are known to be aggressive to their tankmates. You should only keep one of these per tank. They also grow up to 16 inches and can live anywhere from 5 to 8 years!

Electric Blue Lobster

The electric blue lobster make an excellent addition to an aquarium. They are a crayfish native to Florida. These fish will grow to between 5 and 7 inches long, and need at least a 20-gallon tank, according to William S. White Winnetka. They are also known to be very combative and may eat smaller fish in a community aquarium. The Electric Blue Lobster also loves a tank with many places to explore and hide and can live up to 5 years.



The datnoid can survive well in a tank with other similarly docile fish. Also called the tiger fish due to their black stripes, the datnoid originates from Thailand and Indonesia. These fish love plants and hiding spots which allow them to mimic stalking and hunting behavior. However, datnoid fish do not get along well with other small fish as they would be considered prey to the datnoid.


These are only a few of the many types of popular and exotic freshwater fish available today. Each of these fish will make an excellent addition to any aquarium so long as you do not place them in a tank with fish that they are not compatible with, concludes William S. White Winnetka.
