As much as I hate admitting this, you're both wrong. I've literally never sold anybody a pacu since I worked there, I just refuse to. But there's a sad truth, almost all of the pacu we get in die.
I've got a theory that petsmart fish breeders/suppliers purposely send in pacu and common plecos with poor immune systems knowing that if these fish die before they get a massive size, there's a higher chance of somebody buying another one or truly believing they'd be fine in a 75 or 55 gallon tank or whatever crap is spewed on those cards. I think it's funny though, I figured out with pacu and ID sharks only say 75+, it's cuz thats the largest tank most locations stock, haha
