Hello ladies and gentlemen.
I recently acquired son X. pygmaeus. I also have the opportunity to get some X. continens. I haven't found much information about them and when I look at photos, they are so similar or almost the same I would say.
Does anybody know how to differentiate the 2 species? I just want to make sure I have the pygmaeus and also, if I end up getting the contines, make sure they are actually continens.

Here are 2 photos of the fish I got, which were sold as pygmaeus.

Thank you
