agassizii ID & sexing

[DutchyIvo]

Hi all!

A simple question, which I hope is as easy to answer for you Apisto-freaks as it was for me to ask
These 4 little cuties where bought as A. agassizii (Peru WC).

The largest one, about 4,5-5 cm TL

The 2nd largest one, just a tad smaller, about 4-4,5 cm TL

The third in row, a tad smaller than the second one, about 3,5-4 cm TL. This one has a more rounded body shape (a fat belly one could say) and (unfortunately never when you try to take a picture) at time a somewhat cryptic color pattern with lots of black

The smallest one, a bit over 2,5-3 cm TL. This one had by far the most yellow.

Any thoughts on ID and sex?

Look like the holotype form of A. agassizii to me. Sex? Wait until they're older. Males will show a caudal pattern, females will not.

Wow I totally forgot about this one. My apologies guys!
Anyways. Thanks Mike for your insights. The first and second turned out to be males, the two latter are females.
A few pictures are attached for your viewing pleasure.

A few hints of orange in the dorsal and caudal are visible already. Those pics are already a few weeks old, so I guess it's time for a new picture session. Hold on guys!

Looked at this thread for the first time today(tonight!!)..
I almost posted a reply without reading your posting dates!!

This was my answer to be..

"It looks like the 2 first are males (blueish gill-covers) , the other 2 are probably females... My guess!!"

Conclusions... Males often have more colours on the gill-covers...
....and don`t try to do statements in the middle of the night when you are really tired!!

Nice close-up pics.. especially the last female-pic in the first post!!!
