I purchased all 6 at my Lfs and the two known females died. Not sure why as water parameters are perfect. Fingers crossed that a 3rd is a female and not an under developed male. They ordered more for me and got 12 stupid males.....
I see what your saying about a mated pair though. I need more females now but someone else at the store is going to the whole seller and said he would "try" to pick some out for me but I'm not sure he knows what he's looking for. :-(
Yours are very pretty, btw.
