Clown Fish Facts
Family : Pomacentridae
Genus : Amphiprion, Premnas
The clownfish are the most popular group of marine fishes in the saltwater aquarium hobby today. Two of them, the very similar Ocellaris clownfish (Amphiprion Ocellaris) and the Percula clownfish (Amphiprion Percula) are perhaps the most recognized marine fish in the world. Their fame increased after the release of the movie Finding Nemo.
Clownfishes are part of the family Pomacentridae and they make up the genus Amphiprion and Premnas. They are represented by 29 known species with only one member in the genus Premnas, the giant Maroon Clownfish.
They are also known as Anemone fish because they share a symbiotic relationship with anemones in the wild. Nature has given them a way to live within anemones without getting stung. Clownfish protect themselves from the anemones sting by covering their bodies in a type of mucus. In the wild, clownfish will spend their entire lives near their preferred anemone, they eat, sleep and breed around it.
the marine aquarium hobby, they are great fish for beginners as most of
them adapt, cost very little and are very hardy. The clownfish is the
most heavily traded marine fish along with damsels (Also a member of
Pomacentridae) and most species are commonly available. Walk into the
marine section of any pet store and you'll always find at least a few
clownfish and damsels.
The most popular of the clownfishes are of course the ocellaris and percula clownfish, which are differentiated by the number of spines on their dorsal fins.Ocellaris clownfish have 11 spines while Percula's have 10. Other popular members of the family include the maroon clownfish, tomato clownfish and the clarkii clownfish.

Clown Fish : Social hierarchy and gender
All clownfishes are protandrous hermaphrodites, which means they are all initially male and if social conditions are right, they become females. Females cannot revert back into males.
Male ----> Strongest in the pack ----> Female
The determinant of gender change is directly correlated to an individuals rank in its social group. If you house a group of young males together, only the most dominant male will become a female. If she dies, the strongest male will begin transforming into a female and take her place.
Dwarf angelfish (centropyge) Also live by the same rules. In this genus, a female remains a female when dominated by a male or a higher ranking female. Without the presence of another higher ranked angelfish in the harem, she will begin changing into a male.

Clown Fish Breeding
As the most popular marine fish in the hobby, it should stand to reason that it is also the most popular home bred fish in the hobby. Just about every species in the Amphiprion and Premnas genus have been bred at one time or another.
Some are harder to breed and raise, some are easier, but on the whole clownfishes are easiest marine fish to breed. Which is great news because that means eventually, we can stop harvesting them from the wild. The only things that are stopping said scenario from happening are the prices of tank-raised clownfish and the availability of said clowns. There aren't enough tank-bred clowns for the entire market.
As mentioned above, breeding clownfishes is pretty easy as far as breeding marine fishes go. A pair will readily breed in something as small as 10 gallons, however something larger like a 20 gallon is preffered.
The reason they manage to bred in such tight spaces is because they are a site attached fish. Recall how they rarely leave their anemone for any reason in the wild, their entire lives are spent in a small location, their anemone. The same goes for them in captivity. An anemone is not needed, a simple clay pot would suffice as housing.
