Mocha Ocellaris Clownfish (Amphiprion ocellaris)

The Mocha Ocellaris Clownfish (Amphiprion ocellaris) takes the most recognizable fish in the reef hobby and pours a little espresso into it. Mocha clowns trade the bright traffic-cone orange of a standard ocellaris for a deeper, warmer, coffee-toned body, while keeping the familiar three white bands trimmed in black. They sit right between the classic orange and the black ocellaris varieties, which makes them a great way to stand out without giving up any of the easygoing clownfish personality. These are captive bred in the USA, beginner friendly, and completely reef safe. Browse the rest of our saltwater livestock and supplies to build a reef around them.

Why Captive Bred Matters

Every Mocha Ocellaris is aquacultured, not collected from a reef. For you, that means a fish that grew up eating pellets and frozen food, has lived its whole life in aquarium water, and tends to settle into a new tank quickly. It also means no pressure on wild clownfish populations. Captive-bred clowns are the reason ocellaris sit at the top of every beginner list, and designer lines like this one add a unique look on top of that reliability.

Care Guide

• Tank size: 20 gallons or larger for a single fish or a pair. Clownfish stay close to home, so they are one of the best choices for nano and mid-size reefs.
• Water parameters: 74 to 80°F, pH 8.1 to 8.4, salinity 1.020 to 1.026. Captive-bred ocellaris are very forgiving once the tank is stable.
• Feeding: omnivore. Feed once or twice a day with a quality small pellet such as TDO Chroma BOOST plus frozen mysis. Captive-bred fish already know prepared food, so there is no guessing game.
• Pairing: buy two small, young ocellaris at the same time. Clownfish are born male, and the larger, more dominant fish becomes the female. Add pairs together rather than one at a time.
• Anemone optional: ocellaris do not need an anemone to thrive, and captive-bred fish often host a powerhead, coral, or corner of the tank instead. If you want the full show, a Green Bulb Anemone is a common pick for a mature tank with strong lighting.

Compatibility

Reef safe. Mocha clowns ignore corals, clams, shrimp, and snails, and fit into almost any peaceful reef or fish-only community.

Great tank mates include the Firefish Goby, Royal Gramma, Yellow Watchman Goby, Blue Green Chromis, and cleanup crew like the Scarlet Skunk Cleaner Shrimp. Keep one pair of clownfish per tank in most home systems, and do not mix different clownfish species, since they fight. Because a Mocha is still an ocellaris, it can be paired with other ocellaris varieties, such as a classic Ocellaris Clownfish or a Black Ocellaris Clownfish, for a mixed-color pair.

FAQ

Is this fish captive bred?
Yes. Mocha Ocellaris are aquacultured in the USA. They are hardier than wild clownfish, already eat prepared food, and are the easiest way to start a saltwater tank off right.

Is a Mocha a different species from Nemo?
No. It is the same Amphiprion ocellaris as the classic orange clown, just a selectively bred color line. It behaves, eats, and pairs exactly like any other ocellaris.

Will the color change as it grows?
Mocha clowns can shift a little as they mature, usually deepening in tone and showing a bit more black at the edges of the bands. Every fish is slightly different.

Does it need an anemone?
No. Captive-bred ocellaris live full, healthy lives without one. An anemone is a fun addition for an established tank with strong lighting, not a requirement.

Can I keep two together?
Yes, and it is the best way to keep them. Add two young ocellaris at the same time and they will usually form a pair, with the larger fish becoming the female.
