Black Onyx Clownfish Pair

What is the Swell Black Onyx Clownfish?

The Black Onyx Clownfish is named after its beautiful deep black colouring, which varies from fish to fish. Most of these clownfish will have a jet-black body with bright white contrasting stripes, and vibrant orange fins, although some members of this species tend to have more orange colouration that fades from the deep black. Clownfish are known for their lively and social nature and add charisma and charm to your marine tank. Perfectly suitable for beginners, and completely reef safe, these clownfish are highly sought after due to their ease of care and carefree, gentle personalities.
