thats what i thought when i bought it, it tricked me too, but im 100% pos its not socolofi though cause i actualy have socolofi in the same tank and although there stress lines are similar there nothing alike, ive havent seen any mbuna like it thats why i was thinking shes some sort of hap
i think its a she, shes about 4 inches and yes has always been bright metallic blue, the stress line come and go depending on what going on in the tank
