I was wondering how big is the African Marbled featherfin knife fish also.its two pic of the same fish. if I'm not wrong he's about 5ins
ah the knifie fish is roughly 7-8ins. I got two of em right now. One is highly aggressive while the other is more passive. Aggressive fellow actually bit the passive guy for bout a day or so...but now they're best of friends. however, any other fishes i placed in there get bitten and chase about. including my plecos.
with the exception of an ornate bichir who I'm guessing has been able to hold his ground against them. In that if disturbed, he would attack back...
I really doubt so...and if i were to try...It is going to be a very expensive trial for me lol
