smallest knife?

[Connor0729]

hi guys/girls. i have always been into knife fish ever since i got into the hobby, but my parents won't let me get a tank that is big enough for clowns and ghosts. i think. anyways, are there any knives that could live in a tank that is 36" by 18" or so with a capacity of 65 gallons? thanks in advance.

I agree with the Xenomystus Nigri idea.
