I have never really thought about it until today. My friend saw my six 6" Silver Dollars and my two 8" Albino Oscars and asked me am I building them up to be on my dinner plate. Piranha are hunted for food, Silver Dollars are very much like Piranha and would probably taste the same. I know for a fact that Pacu is on the menu in some restaurants, and at least I know what my fish are eating. But the question is ' Would you do it???'
