Hi!! I am just starting to add fish to my tank. Here are couple GBRs. I want to add a third. I am not really looking to breed, but I do want a compatible group. Any idea what the sex is of these two? (I need better photos I think). I was thinking a male and two females (or even two males and two females) would be most harmonious. Any thoughts on that? The one picture next to the orange "plant", its hard to see, but there is a Peppered Cory under the GBR. Almost as if the GBR was protecting it. I think it the coolest thing that everyone is behaving (not sure if the Cory has the same assessment of that :;laughing). Also in the tank are three Peppered Corys (going to add a fourth) and 7 Green Fire Tetras. I want to add two young angels and perhaps another two Rams. All seem happy, but the Rams seem overly shy? I've added these guys about 36 hours ago, is that normal, and will they be more active in the future? They both have found a few choice hiding spots.
