Ive got a pair of GBR's and was wondering whether I could get another opinion on the sex of them. I have a feeling I have a M/F pair and the guy at the LFS said the same. But would like to get another opinion, On the male the dorsal fin is slightly elongated and is forehead is rounded but he doesn't have a black spot so I wasn't sure.
