Black Ghost Knifefish

I have had Abner (my knife) for a little over 2-1/2 years,
He's a wicked cool fish. When I bought him, he was around 4"-5"
long, now, he's close to 13"; almost a keeper! I have the lights
above the tank hooked up to a dimmer, so I can reduce the light
to almost nothingand watch him swim around and eat.
I feed him Freeze dried Krill, it's the only food he'll eat.
I have offered him lots of other food, but apperantly he has aquired
a taste for the most expensive food avaliable.
     I had him in a 20 gal tank but he outgrew after a 1/2 year!
So I received a 55 gal tank as a gift, and promptly moved him in.
I have had a hard time finding any facts about this fish. He seems
really healthy, which is suprising, because I am not a great maintainer
of optimal aquarium conditions! I do more adding of water than I do
siphoning! If that tells you anything. I have a ph tester, but I have
misplaced (not lost) the chart that tells you what your water is doing.
I do know that is is acidic, it is a yellowie color,but it has always
been that color.
 My questions are simple, How big will this fish become? I have
heard that they can grow to be quite huge. Is there any danger
that he will "outgrow" his tank? How long should I expect him
to live?
  I didn't get an owners manual when I got the fish, but I know
that this Knife is a really tollerant fish. I would like to know
a little more than I do know about this fish, but obviously I am
doing something right, because I haven't killed it yet!

       thanks for any replies   H.I. Hasey

I have kept one since 1990 and it has grown from 5" then to 10" now.  

They are nocturnal, so expect to see it laying on its side in some tube/skull/
other hidey hole during the day, except when feeding.  I feed mine sinking
shrimp pellets (Wardley brand), and pond snails when they overrun my smaller
tank.  It has also accepted krill, and neons, head and tail lights, lemon 
tetras, and tiger barbs <ahem>.

I've never trained mine to eat from my hand, but I can pick the fish up and it
doesn't take off.


My tank is a 50 gallon community tank and the thing is still growing.

Things I know or have noted:

1.  They almost never take flake food.
2.  They prefer live food (really live like snails etc.) this is because:
3.  they are electric fish (related to electric eels, but not as 
    powerful).  They hunt electrically, and I am certain I have seen it
    give off a warning zap that other fish can feel.  They should not be
    kept with other electric fish such as elephant noses or other BGKs.
4.  They don't like tail nipping tank mates and will actively seek out and
    destroy the little pests.

I have heard them described as a digestive tract with fins.  This is 
probably appropriate :-)
