If you think of it though...this really makes no sense what so ever. Think of the power needed for the filter and the tank lights, and the money you'd spend to feed a huge fish of that size per year. Then think about just putting a plug on the end of the xmas tree...probably cheaper...then theres the cost of the tank initially and the filter and the fish, could probably run that xmas tree for 40 years for the price of that...
People should put their brains in gear before designing dumb stuff like this...
(D'OH!)
