Can I house two Knifefish in the same tank

[mattmez]

I have been wondering If I can house a black ghost and a carapo Knifefish together

How big is the tank? Some people would say no because fish that generate electric currents can cause disturbances or something like that. I don't really understand it.

It is possible if the tank is large enough..
I've kept multiple BGKs in the same tank..
