Those looking to add color to an aquarium need to look no further than cichlids.
Their bright colors and social lifestyle make them an ideal way to liven up a tank. These are an incredibly diverse group of fish. Each species has its own pattern and coloration, so there is one to suit everybody. They are very active fish. Whenever they sense movement outside of the tank, they will follow it in the hope that they are about to be fed. Another thing to consider is their aggression. They can be territorial at times, especially when mating, which can lead to the death of weaker fish in the tank.
