Cichlids comprise of a large and diverse family of highly adaptable fish, with most of the species being highly desirable in the aquarium trade. Amongst some of the most popular aquarium fish, like the catfishes, they can be found in various aquatic niches from fresh to brackish waters, fast flowing or tranquil waters, and range in size from just over an inch, to three feet long!

Most cichlids though are deemed un-suited for the planted aquarium, as their territorial nature and large size can wreak havoc in a serene planted environment, while adversely some can also feed off vegetation. There are still many captivatingly beautiful species, which are perfectly at home in a planted aquarium, with most hailing from the Amazon, but also a few from Central American and African countries.

Probably the most majestic of freshwater aquarium fish, Angelfish and Discus have garnered huge popularity upon their discovery, and still today share the same fame. Both species lazily and majestically swim through the entanglement of vegetation and are often the focal point of the aquascape. With many colour varieties, and even forms with longer fins, Discus and Angelfish are greatly represented in the hobby. At once considered impossible to keep upon first export, Discus nowadays have greatly adapted to life in the aquarium, and are readily bred in captivity.
