Are they a pair yet?

[Matt850]

I have a pair of False clowns that I have had for about four months. They came from a group of about 20 individuals all about the same size. One is for sure the dominate and I am wondering if there is a way to know when the sex change has completed? It is slightly larger than it's partner and much more aggressive. Two months ago I added a GBTA and they both host it but only in the past week or so. I've kinda been hoping for a mating pair so I could try raising some fry. Any ideas? Are they Mature? Are they even a pair?

The pair was not the smallest I have seen and I estimate they are at least a year and a half old, smallest is about 2.5" and the larger one around 3"

Really hard to say. It is possible that if you acquired them when they were over a year old they have already changed sex. If you acquired two females then they can't change back. Occelaris are the hardest to tell because they are the least aggresive of the clownfish, and thus behaviour alone isn't enough. Unless of course the behaviour is laying eggs

I doubt I grabbed two females. Although possible I guess, it looked as though all 20 or so fish were from the same hatch or at least all the same size. I am basing my guess on age solely on their size and the length of time that I have had them. I guess there are no outward signs as to which sex the fish is? Nothing I can find lets me know if there are any distinguishing characteristics. Oh, and here are the best two pictures I can find of them.

The female is always the largest one. I guess you will just have to wait and see.
