As in terms of personality, I found my acara to be very socialable model citizen. I find most cichlids to form bonds with the owner weather it be for just food or acknowledging that you care for them. They aren't shy fish and they generally don't bully other fish but they can hold their own in disputes very similar to severum temperament. Blue acaras are nice in their own right but personally I prefer green terrors colors and markings to be more vibrant
