Hi Gigio
Welcome to the Parosphromenus Project and the forum. Nice to have you hear.
But,- I am afraid its not really possible to say much about what fish you have, – except not deissneri as you yourself also do not think.
But I would say at least it seems to me that you at least have both male and female. But to say more about which species you need better fotoes 🙂
