My female is the boss of the tank but hides a lot. If you see the big cave on the left hand side of the tank - that's her spot. She's a good tank boss though, rarely ever chases the others and never shows any aggression - even when her male was still alive and they were spawning (I lost her male earlier this year, still sad about it as he was a gorgeous little guy and was the tank boss prior and like her, never showed any aggression even when spawning).
Thanks I appreciate the timely response. She looks great, very similar to my(suspected female) GT. Overall darker shade in comparison the the male but the cheeks stand out on yours very well nonetheless. My well behaved GT is only about 4 inches and I was hoping it would be a male, but now Im thinking of trying to get a smaller confirmed male.
