Black Ghost Knife
Of course assuming there are lots of rock caves, driftwood, and lots of plants.
Black Ghost knifes get a lot bigger then everyone expects. They WILL get wider then the average 90 gallon tank if they are not stunted. They WILL eat (or attempt to eat) anything that can fit in its mouth. This leaves the cherry barbs and corys for a snack for him. (well that is until it tries to eat the corys and gets it stuck in its mouth). Them being an inflexible fish you would need a tank 24 inches wide min for a BGK. The Gold barbs might also be a target for eating, and depending on the loach species. I personally wouldn't do it. If you are i would try to get my hands on a Brown Ghost Knife as they tend to stay considerably smaller then their black cousins. They max out at about 14-15 inches, but you still have the danger of them eating your other fishs.
Knifes are also extremely sensitive to water Params and prefer lots of floating plants to dim any lighting in the tank. Extremely fussy eaters and require somewhere for them to hide that is large enough for them to fit into.
