Based on the shots I've found, the fish I have are far too elongate to be "golden blueface". I think my photo is just from a poor angle.
Take a look at the photo in Konings 4th edition, page 334, of "silver torpedo". The fish I have appear to correspond to that photo relatively well, although mine are not fully mature, and the dark band on the dorsal fin worries me The description on page 332 says "Breeding males of O. sp. "silver torpedo" are yellow-blue with metallic blue head and have egg spots on the anal fin."
I suggest the Cichlidenstadl shot may well be a different fish. Some of the fish I'm seeing on international forums being sold as WC "silver torpedo" appear different again.
I'll do some more digging.
