There are over 300 different species of South American cichlids; you can commonly find many of them at our store. Around ¾ of these cichlids are found in the Amazon River basin in nature. They range in size, color, appetite, and water quality. At Appalachian Tails you will find some of the more popular species of these cichlids, including freshwater angel fish, Oscars, and convicts.
South American cichlids are known for being aggressive but many species can go into a “community tank.” The freshwater angel fish are the most popular among hobbyists for community tanks, as their colors are amazing and are relatively easy to care for. Discus are also found in South America, with spectacular coloring, that of saltwater fish, they are fairly hard to keep and only recommended for experienced hobbyists.
Many of the South American cichlids are ferocious predators, feeding on other smaller fish. 
Certain species can only be kept with fish their own size, like Oscars, because they will eat anything that fits in their mouths. Although they are less aggressive then the African cichlids they can be put into the same tank, but water quality can vary between the two different cichlid types.
To house these cichlids depends greatly on which species you choose. No matter what species you choose though, a 30 gallon tank is the minimum size recommended as these fish can grow large and/or be territorial. Diets for these fish can range from dried flakes and pellets to frozen and freeze dried worms, to even live feeder fish. We feed a variety of foods, which helps keep their colors intense and vibrant. It is always recommended to feed the dried or frozen foods to prevent any possible diseases, but certain predator species need to hunt the live fish.
With so many different varieties of South American Cichlids, we would be happy to help you choose the right ones for your aquarium! Thanks for reading and see you soon at Appalachian Tails.
