How big a tank

[dragonfish]

I do agree with your comments.This was my introduction to fishkeeping many years ago when my folks got a tank. All info was given by the experts at a local fish store. I don't remember they're name but it has been so many years that they may not be around anymore,

yea i would loose the pacu but still you would need a 200 minimum

Adults, all in one tank? 350 min, 500 better, and that is without the pacu, with it 1200 minimum.
