Had a 7-8" male Festae not long ago that would not eat unless I leave the room. But than again maybe it's because he's a WC fish.
Not sure if anyone remembers but I use to own a gigantic pair of Festae, male has huge hump(puts alot of FH to shame) and female with amazing colors. Honestly they were the most amazing looking pair of fishes I've ever owned, ever though they were kinda shy.
