Keeping 2 purple flame

[nanomania]

Hey guys, my lfs had 4 purple flame since 1.5mnths, 2 died, and 2 were left. They seem to be paired up, so i got them both. Its been 2days since i got them, they sometimes are together, sometimes they arent.. have seen then "kissing" but i guess that might be agression.

Any idea on how to determine their sexes?

Those 2 purple firefish are a pr if they have been together that long. There is no clear way to tell apart gender.

So the "kissing" thing is agression or part of....
