thanks for that was a big helptiretrack eels, bichrs, andother fish that arent too small and arent too aggressive. oh and dont compete for food too much.
here's a link for a discusion on it http://www.monsterfishkeepers.com/forums/showthread.php?84850-Black-Ghost-Knife-potential-tankmates
cheersvery nice. you dont want aggressive fish and fish that would fit in its mouth.
I'd be more worried about a Kribensis getting swallowed by the Knife than causing the Knife problems. The Knife has a surprisingly big mouth. I kept a BGK that got to be 14" with a constantly breeding pair of Rainbow Cichlids and had no problems other than trying to grow some of the babies to a decent size! And the tank was shall we say, considerably smaller than 75 gals.so i guess i wont be aloud to have kribensis with it
