I can understand why a conversation about this tank being over stocked would be brought up. I can even see why people would see this video and express their views on fake corals. I even think it's cool if some people don't personally like the tank.
IMHO, when someone says a tank is over stocked, it implies that there's a problem. Like saying the fish are under fed, infested with Ich, or the tank is not well maintained. I would actually like to save this video to show people what a well fed, and healthy fish looks like. The only problem I see, is a slight indication of HALLE on some of the large hippo tangs. IMHO, sadly, it's very rare to see any of these fish, at that size, in captivity, that don't show signs of HALLE. Maybe it's a nutritional thing, IDK, but if that's the only problem I can find, I think they're doing pretty good by these fish.
