I love to see pics of a well cared for pacu. Looking back at all the fish I've kept I can honestly say I miss my large pacu the most. Tremendous fish. I will have to get another one day. I feel for you and understand what you are going through with him running out of room. I had 2 in my 750 and it was starting to get cramped for them after 2 years. Best of luck with him.
