I've never seen those knife fish much above the footlong mark (even in public aquaria). The literature cites the white-cheek at 12-13". I had a pair that reached the 18-20" mark before having to sell them. Not sure of their actual full size.
I've never seen a coldwater american eel and a tropical white-cheek kept together.
