What fish can live with a black ghost knife fish?

I have a 55 gallon tank with a large black ghost knife fish. He seems to have killed off all my mollies and all but one platy. I'm not sure what kind of fish I can add because he keeps killing them all. I also had glass fish, but they are all gone. I have one large snail, an upside down bottom feeder, a ghost shrimp and a 6inch long bottom feeder. I would like to have some fish swimming around in my tank and if anyone has any suggestions I would greatly appreciate it!! Thanks in advance

 

Welcome to the site.

Not many, once the tank is dark they will eat anyother fish they can fit in their mouth.

Welcome to Fishlore, Ness! I have no experience with black ghost knife fish, but it seems Btate has ya covered

 

I would recommend first getting your BGK a larger tank, at least a 75.
Then, I'd suggest cichlids - Cons, Firemouths, etc.
I'm contemplating keeping one in my 150 with my Oscars.
Do you have any pics? ;D

 

A friend of mine keeps one with nw cichlids.

 

I agree with Amanda. CA/SA cichlids would work well (Jack Dempsey, Convict, Firemouth, Oscar, Nics, Severum, Uaru, etc). If you have any pics I would love to see them Its hard to find a BGK that is a good size.

 

Ok thanks for the advice. I actually have someone who is giving us a 100+ gallon tank (not sure how large it is). They just don't want it anymore....crazy right?? So we will just have to move the BGK to that one. I will try to post some pics tomorrow.

 

keep a species tank with just BGKfish. looks great!

 

I have had a ghost knife now for 2 years he is now bout 12 inches he is succesfully living with 2 silver sharks about 10 inches in size and 2 gouramis both about 8 inches and 3 plecs and he doesn't bother any of them
