So after a long day at my LFS I noticed a tank full of blue acaras and after a while of observing I decided to pick up a couple. The dominant male in the tank was one along with two females. After drip acclimating we let the fish into the tank. They look healthy but the male insists on staring at the glasses and puffing up his fills occasionally kicking up some of the sand. I know this is a territorial display but is it normal for him to just sit there flaring his gills?
