my petsmart has pacus about 1in and it says they grow 22'' and minumum tanks size at 125gal
i dont get the minimum thing, its not right for the fish, i think its just to go easy on the people who buy them.
also seem people get over confindent when buy a baby monster, and they cant seem to grasp the reality of how big they grow and the care they need.
one last thing, i think when they label the fish in petstores they should label the TRUTH about them, that way it will drive away dumbasses and noobs and draw in committed aquarist willing to give their monsters what they really need.
thats just IMPO.
