Aquango - blog solution for aquarists

Aquango.com is a free web blog system, but it's not average weblog - it's the place where aquarists can show off.
They can submit photos, write about aquarium and even measure temperature and display on graph. But, it's not all, Aquango is open source - php code available over SourceForge.net
You can obtain aquango demo blog here or check phpaquablog - open source system for your own.
Great aquarium gallery.
