Possibly the best aquascaping rock in the world...

That's right and I believe Dragon Stone could well be the  best aquascaping rock in the world and for 3 good reasons:

1) It looks lovely. The colours and shades are what makes it so unusual. The brown hues provide instant calmness and impact.

2) The holes/crevaces, call them what you like. I mean, who has ever seen holes in rocks before? I haven't especially on this level of consistency. Again another unique feature of Dragon Stone and what separates it from all other rocks available.

3) Ease of aquascaping. The varied sizes available (especially at this moment in time) means you can create a terrific aquascape in no time with little experience, as long as you choose enough. Don't fall into the trap of buying a few kgs and expecting a miracle. It doesn't work like that. When pros aquascape they normally choose from a few hundred kgs. I'm not suggesting for a minute you need this much (on the contrary) but 2 or 3 kgs rarely cuts the mustard. Aim for 10kgs and up.
