black ghost knifefish with cichlid??

[anthonylam]

hi i have a 55-60gal. i was thinking of having a black ghost knifefish in the tank. then i also thought of adding an oscar or a green terror(aequidens rivulatus)... which means... 1 black ghost + 1 large cichlid.

after doing some research... it doesn't seem that i can have a large cichlid in the same tank as a black ghost. what do u think? pls give me some feedback. thank u.

I'm not sure why it says that they shouldn't be kept together, I think the BGK is too docile for aggressive fish, and may get picked on. Plus the species profile on this site for the BGK says a minimum of 90 gallons, so your tank isn't quite big enough anyway, especially to try to house supposedly incompatible species. Also, be careful about what type of cichlid, some get too big even for a 60g tank ;)

well, the species profile of bgk on other sites say that 60 gals would be enough for an adult... about 40cm... anyway.. if i had a tank with 3 silver dollars, 2 striped raphaels, and a sailfin pleco... and have space and the intention to add one more fish...
would it be oscar or green terror or black ghost... which would have more personaltiy? all grow to about 12-16 inches.

BGK like to sleep all day. They do have wonderful personalities, and you can train them to hand feed. But if you are looking for something more active, go with the cichlid. You will have to get your hands wet anytime you want to show off the knife. Since the BGK is practically blind, it will have problems defending itself against the more agressive, and optically advantaged beast. If you absolutely had to do it, make sure to have a good slender hiding place for the knife
