Freshwater Fish

The most popular of fish keeping, such as goldfish, guppies and angelfish.


Bright, colorful and great to watch.  Because of their size, you can have a few in one tank, they are schooling fish, so they like to be kept together.  They love tanks with plants in, so you can really jazz up your tank by adding attractive plants.  They have a sheen and they will seem to glow if the tank has a light, making the appearance even more attractive.


Peaceful fish that grow to about 4 inches.   The male species can be aggressive toward each other and they breed very easily.   If you do happen to have babies, make sure you remove the female as they do have a tendancy to eat their young.


Sometimes referred to as the millionnaire or rainbow fish. They school together and feed mainly on algae.  Although mainly a freshwater fish, they can be included in marine tanks.

They are susceptible to poor water conditions.  They do like a heavily planted environment.


These beauties add color and finess to any tank.  They originate from South America and are naturally carnivorous, so it’s important they are fed the correct food.    Flakes or pelleted food with occasional live feedings, they can grow to nearly 10 inches.  They are generally known as a community fish, however, as they become older they can become aggressive.
