Need some ideas for 180g

[duanes]

I agree with the others about not mixing Central Americans with South Americans. Many Centrals are on an entirely different aggression scale and territorial level, than their S American counterparts.
I also believe that once your fish grow into the tank, it will be full. And it won't take very long, so if you add many more, water quality could suffer, and aggression become a problem, when they are packed like sardines.
I also consider Geophagus braziliensus from more southern South America to be a more cool water fish (low 70s, even into the high 60sF) and when kept too warm normal tropical temps, become highly aggressive.
The area in S America where the braziliensus complex is found compared to your other fish, is further relatively speaking than Toronto to Miami. Not quite as drastic in temp variance, but worth considering.

Just to clarify, you mean the 180g would be full with the two pikes, Myersi and a chocolate?

I totally forgot about that, thanks for making that clear Duanes. I believe there is another variant that is found in a hotter climate though? I spoke with Jim Cumming about it on youtube once.
