I have seen one grow to about 18 " in a 55gallon tank- one things I have noticed through my experience is they tend to grow somewhat slowly. I currently have a baby that I bouhgt not quite two years ago, it was nose to tail maybe 2.5 inches, and now it's pushing 4 inches. It eats everything I drop in there, frozen or dry food, loves all it's caves, glass tunnels, plants and to swim upside down whenever in the mood.

I have had some that when put into a tank with tetras the tetras tend to lose thier eyeballs at night, and small things like neons or guppies might disappear. Other than that, they seem to not be very fierce predators, and are very safe for general community tanks, minus small tetras.

Most of the ones I have seen that are more than 12 inches are more than 10 years old.

They are electric- and terretorial towards other electric fish- I am amazed that the elephant nose and the black ghost are getting along in the pictures posted here.

They had one on Abyss that was HUGE. I believe that they inherit a smaller size in the home aquarium due to their inability to "sense" food. If you ever watch them in the dark they are constantly savaging for small shrimp, snails, and critters. they are probably in a constant dark in the wild and eat a lot more.
 
Thanks for all the info everyone. What I'm trying to get a grasp on is: what would be a good sized tank to keep one for life with no other tank inhabitants? Would a 40gL eventually become a torture chamber in say, 8 years?
 
Yeah they get freakin huge, my ex gf's is like 12 inches long and it's kept in a self contained jebo tank...i'd love to put it ina larger tank and watch it sprout out!

look at this monster...and no its not hers! :)
