when are people going to learn that the more pacu you have, the more digits you need in your pond gallonage
3 pacu will be at minimum 24" each within 2 years, even with only mimimal care. do you have any idea how much space those 3 fish will take up?
now imagine 3, 24" pacu getting spooked in a tank thats too small and all ramming the sides of their enclosure. indoor swimming pool anyone??
hopefully you already know all this, and have a tank/pond pushing, or over the 1,000g mark
