Dumb Question, but I've got to ask
 

I'm using Beta 7k with XP Pro and an ATI 800XL with no problems at all. It runs fast and smooth even with all the fish selected. Although still in a beta version, this is the best sceensaver available of any kind.

I do have a question. Keep in mind I really enjoy "Marine Aquarium 3", but I am a dummy when it comes to knowing anything about salt-water creatures, plants and fish (OK, everything). So, what is the green "W" looking thing in the bottom of the tank? :confused:

Thanks

Green bubble coral (Plerogyra sinuosa)

The bubbles are currently withdrawn. When it's finished, they will be normally extended, then retract when touched by a fish.

Wow, within minutes of posting a question I receive the definitive answer from the SerenScreen creator himself. :)

Thank you so very much.
