Critique - and what are the stains?

[dvdrew]

I'm new to discus and currently have 4. I get confused about the stains as different LFS label what appears to be the same discus, different names.

What strains do you think I have and what are your critiques? I need to know what is a good discus and what is not so don't hold back!
