The Ocellaris clownfish are great hardy beginner saltwater fish. Clownfish do not have to have anemones to live in but may host in LPS corals like Frog Spawn and some soft corals if an anemone is not provided.
Ocellaris clownfish are commonly thought of as a Clown that has an orange base color with three white vertical stripes on its body and black tips on the fins. There is a morph to the Clownfish species that has beautiful black color instead of the orange.
Captive bred Clown fish specimens are commonly available in the saltwater aquarium trade and are to be preferred over wild caught specimens. Captive bred fish are hardier and easier to care for than wild caught fish and will therefore significantly raise your success rate in keeping them. Other reasons are that captive bred fish due not impact wild populations of fish and captive bred fish due not go through the collection and shipping stresses that wild caught fish go through.
The Ocellaris clownfish can be kept with most other saltwater fish but should not be kept with other Clownfish species including their own unless they are a bonded or mated pair. The Ocellaris clownfish can be aggressive in protecting its territory. This happens more when it is hosting in an anemone, it will chase any other fish that comes close to the anemone and this can include the hand of the aquarist.
Ocellaris clownfish are an omnivore which means they like both algae and meaty food in their diet. They are also easy to feed and will accept most foods including commercial marine flake food. A once a day feeding is usually adequate unless you are trying to breed then and in that case may want to feed more frequently.
Ocellaris clownfish are one of the easier saltwater fish to breed and can be done without the presence of an anemone in the aquarium. Sexing Ocellaris clownfish can be done by the size of the clownfish. Males are smaller than the larger females. The eggs will be laid on a hard surface that has been prepared before hand by the clownfish pair. The fry a very sensitive and will require special food and more frequent feedings.
