I just recently purchased my first knife: a (now) 5" ABK. Not as interesting to look at as the royals, but he's the right size for the tank he's in. Mine's shy, but when he's out, I love watching him swim.
I remember My first knifefish. I deathed out my tank (turned everything black) and got some dimmer lighting and he was out all the time. But afew months later my wolffish killed him
