My apistos had a few spawnings which resulted in many fry. At what age/size will I be able to sex them? Also, at what age/size will I have to be concerned with aggression and teritorial behavior? I want to keep a male and a few females for another tank but I wanted to know how much longer I will have to wait before I can tell what I want to keep and what I will sell to my LFS....

From what I remember with the Apistogramma, when they get bigger say 3 to 4 months, you will notice the male has a bit brighter color and a pointier tail fin. He will also be larger than the females. Pictures would be nice to see.

Could you let me know if you are able to see the whole album by clicking on the thumbnail?

Also, I would appreciate some more responses to my original question. :)

I don't know the answer to your questions, but I can see 11 photos in the album.

Nice fish!

You should be able to see differences in a couple of months or so. Males will be slightly larger (even at this age), they will have generally longer finnage (particularly the dorsal) and they will have brighter colour, you should be seeing red or orange by this time in some of the fins (mainly dorsal and caudal). The females will be drab, a grey/yellow base colour, smaller and their fins are more rounded. There tends to be more females than males - anywhere from a 2:1 to 16:1 ratio. Some believe that pH, temp and other water chemistry have a bearing on the ratios.
