At first, Bob, I wasn't even sure that these fish belonged in the agassizii-lineage. But the last two photos show the distinctive metallic blue spot on the corner of the mouth. I don't think that they are A. paucisquamis females. Female pauscisquamis have a more distinct pattern on the tail fins and a black blotch at the anus. I don't think it is any of the species in the paucisquamis-complex (A. paucisquamis, A. mendezi, A. sp. MiuÃ¡, A. sp. Gabelband/Fork-band). Females in all of these show fairly distince horizontal stripe(s) below the lateral band. Yours don't. Then I looked at the white belly region. They all seem to show little in the way of scales along the belly between the ventral fins and anus. This is a feature diagonostic of A. gephyra. The broad lateral band is typical, too. I think that you have A. gephyra females.
As a comparative, here is my other potential female. She came in with my male paucis several months ago. When I got the group of 20 fish, none were sexable. All but this one turned out to male. I'm not positive about her being a paucisquamis either, but I see more potential. The photos don't show it, but sometimes I think I see the black anal spot, sometimes not. Also not evident, but sometimes during displaying and challenging, her fins, namely caudal, will take on a dark pattern of vertical rows of spots. I witnessed this yesterday when I tried to introduce the two females, while the gephyra (?) showed nothing similar.
Bob, you may have helped me out in another area. I have two lonely male gephyra that have no mates. I may be able to fix them up now. Now if I can just get the paucisquamis figured out.
Zack, your fish shows a disinct horizontal stripe below the lateral band. You can also see the scale (some dark-edged) along the belly, too. Your description of the caudal pattern (not visible on your photos due to the net) all seem to indicate that the fish is a female paucisquamis.
I am still not absolutely positive that Bob's fish are female gephyra, but from the photos shown, that is what they look like. It would be nice to see if they have any caudal fin pattern at times.
If that's true, that's great news. I was rather disappointed, to say the least, when one by one the others kept showing males characteristics. This gives me some hope. The males are gorgeous and have a very nice orange chest region.
If you look in the last couple photos I posted of the potential gephyra female, you can see some faint speckling. There is some faint patterning evident. I can always give it a try with the gephyra males. They're quite nice as well. Incidentally, these male gephyra came in with another group of paucisquamis I had gotten ealier. Perhaps gephyra is a common by-catch? This would explain Bob's situation as well....it's all becoming clear...
