Yeah, that sounds about right. I had a fish like that, Maccaroni, who was so neurotic and obsessed that he rubbed his face raw on his (rather soft) divider, trying to get at the other fish.
He needed to be removed and put into his own tank because of this...Its sad.
Even when he was in his own tank, he would literally spend HOURS going back and forth and doing the same things over and over. I felt terrible for him. He's a little better now, but I know this affliction will never leave him.
