IMO firemouths just pale in the first pic, the fish in the center of the picture is definatly a FM i have 2 and you can see a bit of orange on its chest. THey are all FMs accept the one fish in pic 1 above the FM in the center, it might be a FM or it does kinda look like a RD. But since it is the exact same size as all the other fish, same color accept the black spot, but other that that, FM body shape and finnage, just weird colors.
