I saw him, and just had to have him: D Since I was just busy anyway with the refurbishment of my 112L aquarium, the time was favorable. The skull itself looks visually very good, also the workmanship is alright. But if you want to use the oxygen diffuser, you can not see on the picture, I can advise only. The oxygen bubbles accumulate in the skull, so it sometimes makes quite a "Blubb" if after some time then flows a big bubble. If one the skull without weighing the water, it raises even from times or shifts. So I installed the vents taken out and placed behind the skull. Now everything fits. It also looks pretty good, if you let a high-growing plant of one of the eye sockets grow, only as a decorative tip;) I have to say that the size of the article exactly for my already mentioned 112l Aq. fits. I fear with larger pool he goes down just as the saying goes. In my 240l Aq. I had used him sample white, there he just made a not so good impression.
