yah after looking at them the major difference is the black. how long does it take the to sexualy mature? when will your mate? i would love a baby cinnamon lOl
Ok, after a little bit of homework it looks like the truth is somewhere in between. Your right Bellamy, all clownfish are biologically male but they are considered gender neutral, or sexless, if they are not the dominant male because they dont exhibit any sexual behavior and they are potential female clownfish. Here is a nice little excerpt that i think sums it up rather well.
You need to get a pair if you want to breed clownfish, and that's quite interesting - believe it or not, clownfish are all born as males! When they are adults, the largest and the most dominant fish of the group will undergo a sex change and become a female. The second largest usually becomes the breeding male, while all the other fish remain juveniles and gender-neutral. If the breeding female disappears, the breeding male will change to a female, and so on. Buying an established pair may be a reasonable way to go, but it is often better to have a group of juveniles growing up together. If you choose to buy a pair you should look for a pair that goes around together. Sometimes you can be lucky enough to get a pair already spawning. Anyhow, establishing an adult pair can be a little tricky; and you need to keep your eyes on them to make sure that the female doesn't kill the male.
here is another very interesting fact about how precisely clownfish regualte their size to accomodate their place in the group heirarchy.
orange and white patterning, has found that hierarchical boundaries are so entrenched in their "culture" that subordinates control their size and growth rate to the millimetre. When the position at the top of a group becomes vacant, social climbers will go as far as changing sex.Clownfish reside in discrete groups dominated by the top- ranking female breeder. Her lower-status male partner is next, followed by up to four progressively smaller and lower- ranking, non-breeding subordinates.
“We found that as you go down the social rank, each fish maintains its size at 80 per cent that of the one immediately above it - if a fish ever grew too close to the size of its superior, it was immediately rejected,” said Peter Buston, who led the research at Cornell University in Ithaca, New York.
When the dominant breeder in a group dies, all the fish move up a social level. The top male changes sex to become the primary female, the top-ranking non-breeding subordinate becomes a sexually active male and all the other subordinates shift up a rank.

Well, mine are going on a year old now, and generally they need to be at least 2-3 to produce eggs. It is affected by diet a lot, and the healthier that they are fed the quicker they will breed. Ours mainly get flake with the occasional mysis, so it may be a couple years.
