..I have my very own aquascape tanks that are heavily planted, and look decent, but nowhere near as godly-good like those. Those nature iwagumi aquascapes are freaking amazing. I'm jealous.. those tanks are like complete, perfect, total eye-candy tanks, and so darn impressive anyone would have their jaw drop if they see the tanks in real life. Very inspirational to me, and at the same time mind-numbing how they get the tanks to look like that.. must've been a hell of a lot of work and time to plan out the focal points, the right substrate used, the certain types of plants used, the slopes and heights on the back, the right kind of sand/rocks and the sizes used, driftwood pieces, certain scaping rules.. a lot of stuff comes into play when trying to get a nature scape going, you're pretty much trying to do your best to imitate nature.. it's difficult to get going, unless you have the experience, gone through a lot of competition and know what you are doing.
Anyway thanks for sharing the pics, Andrew.
