It sounds as if you have one terminal male, one submale, and two females. You have a couple of possible scenarios. If the male is perceived to be weak (many do not ship well), the male in waiting will bump him off, but you may also have stasis. I hope the latter is the case.
From reading this it seems better to buy a pair versus a harem when it comes to flames.
That may have been the issue. While all three females adapted quickly, and ate anything and everything, the male was shy, and didn't really eat well for the first week or two. Hopefully now that he is just as well settled as the females, he can keep his dominant status.
But I never see females offered for sale -- stores want the males, because they are the super colorful ones. I doesn't seem as though wrasses are offered the way anthias are -- based on gender. There are quite a few beautiful female fairy wrasse species. I just don't know how to obtain one.
I bought 5 female flame wrasses. One quickly became "super"- male. Now one of the other females has changed to sub-male. They have been like this for awhile with no problems. I watch them closely and is there is any aggression between the two.
I plan on removing the "weaker" one, if I see any signs of aggression. IMO if they can co-exist they should be fine, it's only natural to have a sub-male in waiting. If you have two males than your asking for trouble and one needs to be pulled out.
wow... from female to supermale?I have seen a supermale evolve in as little as two weeks.
