XXL Black Ghost Knife?

[NicMe]

Recently found out a BGK I rehomes 20 years ago is still kicking and needs to be re homed again... currently in a 55 gallon and 15 inches long.
any idea if its would be a decent tank mate for discus?
Currently have 6 5 inch discus in a 90 gallon.
4 of them are paired off and kind of feisty.

I don't think anything 15" long should be in a 4'-tank, much less one with discus.

people sre starting to eat those babies. If you search knife fish they also have catch and clean videos. Apparently good on the bbq, who would have thunk it.
