Description

The Domino Clownfish (Amphiprion melanopus variant or Amphiprion ocellaris designer morph) is a striking addition to any marine aquarium. Known for its deep black colouration and signature white dots, it’s a hardy choice for both novices and seasoned enthusiasts.

Appearance and Behaviour
The Domino Clownfish is a "designer" morph, typically bread to be almost entirely jet-black with only the white "domino" spots remaining on its head.

Colouration: As the fish matures, its black colour deepens. Unlike some other species, this darker pigment is quite stable.

Temperament: They are generally peaceful but can become territorial once they’ve recognised a specific anemone or coral as their home.

Socialising: They thrive in pairs. If you introduce two at different sizes, the larger one will usually organise itself as the dominant female.

Minimum Tank Size:  75Litres
Water Temperature: 24°C – 27°C
Salinity: 1.021 – 1.025 specific gravity
Carbonate Hardness: 8–12 dKH

Dietary Needs
In the wild, clownfish are omnivores. In a home aquarium, a varied diet is essential for maintaining their lustre.

Pellets & Flakes: Use high-quality stabilised vitamins and marine-based proteins.

Frozen Foods: Mysis shrimp and brine shrimp are excellent for protein.

Algae: Ensure their food contains some vegetable matter (like spirulina) to mimic their natural omnivore diet.

Choosing an Anemone
While not strictly necessary, providing a host anemone is a favourite pastime for hobbyists. In Australia, the Bubble-tip Anemone (Entacmaea quadricolor) is the most popular and accessible choice for a Domino Clownfish to colonise.

Pro Tip: When cleaning your tank, be mindful that clownfish can be quite cheeky—don't be surprised if they try to "defend" their anemone by nipping at your hand!
