Yeah they def take some time to warm up I will say that much. I remember getting them for the first time they did exactly what you are saying laying on there side and pouting for quite some time. Dont get me wrong, they are not like a midas when I say they will hold there own. They just are not like the domesticated O's where they are easily bullied. I had one in my tank with my green terror and it took no guff from the GT it was more than willing to fight back. Mine really didnt harass anything kinda kept to himself and was more than happy to eat.
