Sexing GBR's

[help me]

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.

Male:








Female:

Yes, this looks like male and female to me.

Agreed, the pink belly is generally a pretty accurate way of determining the sex of these fish.

I'd just add however that Blue Rams demand higher temperatures than most other tropical fish, 28-32oC is best, I can see in the photo that you have neon tetras, which are unable to handle these higher temperatures making them incompatible.
