That's a nice erythrinus looks pretty big too
Usually the case when larger. Only time I experienced other wise was when I introduced a purple wolf to a gold wolf. Purple joined the gold in the upper region of the tankThanks. I would say he is close to 7 inches or so but quite round. Unfortunately the tank probably makes him look larger. He's in a 20L at the moment which isn't ideal but he's kind of a log most of the time. That is until I approach.
