The Emerald Cichlid, also known as the Chocolate Cichlid (Hypselecara temporalis), is a large, South American freshwater fish known for its stunning color shifts from deep browns to vibrant reds, oranges, and greens, often with a prominent black spot and large eyes, making it a popular, generally peaceful but sizable addition to community tanks with similar fish like Discus and Angelfish, needing spacious setups with driftwood and soft substrate.
