Have you ever seen Asian Rummy Nose? I recently saw them for first time. I think they are gorgeous. Some lfs will call Asian Rummynose Tetra but I'm sure it is not a Tetra since it is missing adipose fin which is characteristic of Family Characidae. I believe they are some sort Cyprinids ( Rasbora ).
As far as German Blue Rams, if not sure how to sex them, one way is to stand in front of tankful of German Blue Rams at lfs. In NYC, very common fish and some lfs has in great numbers in one tank. what you can look for is pair that may be bonding or mated, trying by taking over one corner of tank, chasing away all others.
If you happen to see such action, ask the staff to put the container toward the corner they have taken over and chase them into the container. This way you know you got the possibilities of increasing number of tank at home. If chased them with net, you may not get the same pair since will blend in with other Rams. Males are usually larger and more brilliant in colors. Dorsal Rays are another method to distinguish but it would'nt be easy w/ German Blue Ram.
Another method is the shape of breeding tube (sharp for Male and blunt for female) when they are breeding. I can't seem to remember the term for it since I been out of breeding for a while and getting older.
LMK if you need any assitance. More than happy to share what I learned from my experiences with fish for about few decades.
Good luck and Enjoy the beauty.
