I added new movie with English commentary: Aquarium layouts of Nature Aquarium Academy, Łódź, Poland - pt. 1
This is the 1st part of a whole series of movies, next part coming soon.
And here are some slightly older movies: Aquarium layouts of ZooExpo 2011, Warsaw, Poland - pt. 1 Aquarium layouts of ZooExpo 2011, Warsaw, Poland - pt. 2
The 2nd part may be interesting for you, as those are some nano-aquariums arranged for aquascaping contest (although not the best ones - those are just the first 10 nanos out of 40).
