Can a black ghost knife live in a 40 gallon long?

dang...that's a healthy growth rate.
 
The fish was in a 29 while all this happened.
 
lol
 
The last one I kept went from 3" to 14" in about a year.

It seriously took mines 4 yrs to grow to 11-12. I'm having a hard time believing this one but it's not to say that you're lying.....:what:

You don't change enough water.
 
Might keep that info to yourself..

You told the OP not to do it, then you say you did it in an even smaller tank.
I did it by changing 1/3 to 1/2 of the tank 3 x a week. Anyone who feels up to that level of maintenance should also feel free to knock themselves out!
