ok I have seen vids of what pikes can do to other fish I just really love their looks are their any other center peice cichlids that have some what of the same personality I mean I love my polys and cats but when It comes to personality their is nothing like a cichlid
Green terrors are close to being like an oscar (personality and aggression) but generally stay much smaller. You'd get overstocked bioload-wise adding it with the other fish in the 75 g once it gets to about 9". It would require more than 1 fin level water change a week.
