I'm not an "expert" on BGK but I have had one for almost 4 years now and I can say with great certainty that they are quite friendly with other larger fish. Mine lives with 2 large angelfish, a tiger barb fish a couple of bottom feeders and a Plecostomus algae eater. All are healthy and happy and alive. However, I did make the mistake a while back when I purchased several guppies (cute colorful small fishes) and within a few days they had all disappeared. So yes the BGK did kill them but I think they were mistaken for lunch. Basically if the fish is small enough to be eaten by the other fish then it would be unwise to put them in the tank. The BGK has a deceptively large mouth. Also they can be aggressive when placed with other BGK or fish within that Knifefish family. In that case they should be separated in separate tanks. If the tank is big enough (has to pretty large) where the 2 knifefish's can each claim their own territory then it might not be so bad but still probably unwise. I have read that it can be done. Also, because they rely on their built in radar to find their food, having another similar fish can make it difficult for them to find the food (something about frequency being jammed or something to that effect). Makes it harder for them to locate their food.
