Sorry I should have probably said to start with, he was told these were dwarf gourami. Is this correct? Can you get dwarfs this colour?
It is the shape--these could not possibly be dwarf gourami, but I don't think there is a gold colour dwarf. But these fish have the longer and narrower profile of Tichopodus trichopterus, which is now available in many different varieties/colours.
Don't expect store staff to know anything. I had a person in one store once tell me that the four pencilfish in the rummynose tetra tank were Siamese Algae Eaters. I knew exactly what they were, I just asked her for the price, and she said they were SAE. The mind boggles.
Edit. Essjay posted as I was typing, same info.
