Hurriken-- I'm glad I can be some help, though I wouldn't look at this as an example of the best way for growing aquatic plants. As for the rocks, There are better defined rules for iwagumi. This is not iwagumi, and for the most part I tried to just use them to set the basic shape and support the plants. Therefore, there is not "main stone." However, it is good to stick to the most basic ideas-- odd number of stones (2 and 4 are usually bad though 6 or 8 might be ok), keep some empty space, and use smaller stones to support larger ones.
schaadrak-- I sympathize with your AADD.

I've never done bonsai so I wouldn't know about that but, I have seen bonsai trees kept in terrarium before (in photos).
This "style" is new and old. In a way, it's just ikebana but with plants that live and a dish that's clear.
KyCox-- I did water changes every other day. Nu'uanu (my home valley) water is very good.
Studying in Japan was exciting. Tokyo is a gray place but it's bustling with life and a sub-concious level of culture. For me though, the really special times were those I spent with my Dad site-seeing. One thing an aquascaper needs to do is reach out and absorb the beauty and cues from nature. Japan was truly inspiring.
From casual things like staring out of the shinkansen window to catch a quick view of a misty forest of bamboo and sakura.
Over-powering things, like the mind-numbingly beautiful garden grounds of Ginkakkuji, whose designer is still considered a genius by the people of Kyoto centuries after its creation.
Small things, like the cool sweet water of Koimizu, and seeing riccia and mosses bubble at the base of the pool there.
Calm things, like taking in the sight of cool green maple trees at Miyajima island from a Ryokan window while drinking cold sake.
And of course, grit-driven and determined moments like walking around rise paddy are (in the middle of nowhere!!) where no one spoke a lick of english (my Japanese was severely tested), in the pouring rain, looking for this "Nature Aquarium World Gallery" that's supposed to be around here
somewhere. We did eventually find it-- we ran into a nephew of Amano's (believe it or not) who took us to the gallery.
