JHardman, Thanks for the reply. I will introduce all of my other fish first, and then the female GSM, and then start looking for a suitable mate.
I do have one more question concerning the timing of sex changes. From your multiple replies above, it seems that age is the determining factor concerning when they can begin to change sex, is this true? I ask because I sometimes see small (less than 1" nose to tail) GSM clowns with their stripes already a bright yellow color. I think you mentioned that these are probably WC, and could be 10 years old already. I assume this means they can change sex pretty quickly, even though they are only 1" long. Thanks again for this very informative thread!
You got it. There are two requirements for a sex change, first is being physically mature, which is strictly an age based thing. With clownfish, depending on species physical maturity is reached between 12-24 months. Second are the environmental factors of dominance.
So it is quite possible to have a 3/4" clownfish that is 30 years old and sexless, as it has spent it's entire life in a hierarchy and never been in a position to be sexual.
A physically mature clownfish can change sex in a month. This was documented by Joyce Wilkerson in her early days of breeding when she separated a pair to ââ"šÂ¬Ã…"œgive them a breakââ"šÂ¬Ã‚ only to find she had two female instead of a male and female.

PS: my local fish store says they do not like to carry captive bred clowns because there is a very high incedence of deformaties like flat faces and misbarring, caused by inbreeding. Is there any truth to this?
Not Mark, but I will put in my $0.02 on this one. This is a typical cry of a LFS that doesn't want to spend the extra money for CB clownfish. There is some truth to the statement, but by in large it is a false statement. Any breeder worth their salt culls deformed fish and never sells them. And many do offer mis barred clownfish, but as a separate, graded product, at a different price, generally less, sometimes more based on consumer demand. So when you hear a statement like that, it is either based on misinformation and lack of experience or flat out greed as CB clownfish run about twice as much as the same WC fish, allowing the LFS to make more money. I have nothing against an LFS making money, if they didnââ"šÂ¬Ã¢"žÂ¢t they wouldnââ"šÂ¬Ã¢"žÂ¢t be there to serve our needs, but putting BS like that state out there I do have a problem with, it is at best misinformation and ignorance and at worst a flat out lie to make more money.
To the general question of rather there are more mis bars, deformities in CB clownfish versus WC clownfish is one that is not likely to be solved. But one can make a logical argument that the rates are the same in CB fish as WC fish. For example, a fish with a deform jaw... In a CB environment that fish will likely be able to survive to a large size, while in the wild it will likely become food for something else or starve. Keep in mind that just because you do not see as many WC fish with mis barring and/or deformities, doesn't mean there were not a lot that were hatched out, but simply did not make it to ever be caught for sale to you.
