Good to see someone else is having success with this, and I really think it's because you got yours at such a small size and it grew up with other fish. The fahakas reputation for aggressive is, I believe, mainly based on the fact that up until only recently most fahakas were wild caught and arrived in Lfs around 2-6 inches. By this point they have learned the savage aggression from the wild in which they live in very murky water and anything they see is either a) food or b) a threat/rival so they immediately kill it. I will post some more complete pictures of my tank after the water change has finished so you can see who my own lives with and how calm she is.
