Tbar - Very nice, excellent quality BG and a great testimony for Optimal Fish Food. Those fish are well on their way to trophy status.
I think the 1st fish is a female and 2nd fish is a male. Notice the different shape of the opercular flap. Gular area is darker on the male than for female, a normal feature.
