can they be kept with a BGK? there are about 4 hiding spots in my tank, but my ABK is occupying one of them, inside an ornament. i tipped it over so i could see what it was going all the time and it just made it easier for him, but im wondering if they would get along or not. cuz id like to get a BGk, but i have some swordtails in the tank, but i think itd be a while b4 he got big enough to eat them. plus i need another fish help eat their fry :p my tank is mostly angelfish, i have 7, but i have 1 male and 3 female swordtails. and a blue gourami, but i dont think hell have a problem of getting eaten

I had issues with anything more than one knifefish. They are very slow growing, I wouldnt mix them with an ID shark. The dominant one in my tank was always the smallest one, and when it looked like they were s tarting to get along, the bigger one was dead.

I have a 20g tank with a male bata, red tailed shark, female bata, angle fish and a rather large African brown knife. I'm amazed that they all are so peaceful, no fights and the nocturnal knife fish is over joyed with the random company. He actually leads the smaller fish around like they are a community of the same family of fish. Is this normal or am I just extremely lucky?
