I dunno, it's impressive but it will inevitably fail. We talked about people buying arapaimas in another thread. Unless you're pfc or arapaimag who have tanks that are not only in the thousands of gallons range, but also wide enough for the fish to turn, you cannot successfully keep these monster fish. Please dont take offense to my post. I just respectfully disagree with how this tank is set up. I could be called a hypocrite with my peacock bass in my 125 gal. tank as a juvie. My excuse is that I'm moving him to a 300 gal. tank at my school or back to the fish store's 400 gal. tank. anyways, i dont mean to insult, I just disagree.
