Wow!!! What backbreaking work. Now all he needs are some Spongebob squarepants ornaments... ;0)
I am disappointed that, after all that effort, he didn't use some large fish; I guess fish seem to be the afterthought! I thought aquariums were for fish? I do understand the point of scale, but there is so much swimming room in the tank, he could have schools of mid- and high- level swimmers.
I NEED those substrate holders he's using. After every cleaning, the substrate in my tanks is leveled.
