His point is that if it survives that long then it will be one of the longest lived ever in captivity and has suburb genetics, prestine care, perfect water conditions and no self inflicted death which sadly ussually doesnt all end up perfect. Yes the pacu could outgrow one of thse but if he has the ability to have two 400 plus take then i think.he has the means to give them a small pond or something of the nature if it came to it. This seems to be such problem here people see a 300 plus tank with custom stand and self done filtration and its assumed that the person who just dropped god knows how much money doesnt have more if they need it. I can almost promise the op is well suited to caring for any sort of fish life.
