I saw this http://www.msnbc.msn.com/id/26786412?GT1=43001 on the net today and thought it was interesting. I would just like to share with those that haven't seen it.

There certainly is a lot of life on a reef! My reef is only 12 gallons but it must have at least 100 species of life in it most of which came with the live rock and live sand so I didn't technically buy them directly.

So you paid for the rock and the sand and got some extra creatures. How cool is that!
Everytime I go to the petstore I just stand there and stare at the saltwater tanks. They are just so facinating. They are full of new things to me anyway. I really like those pencil fish and the corals. They really look neat! In my spare time, like to look at the DF&S saltwater fish pages too.

You'd think I'd stop finding new animals by now in my reef tank since it's 5 months old. I saw this thing pull back in to the rock last night. I think it's a peanut worm. It's a small fat bodied worm with no tube that lives in the rock and retracts back in when it sees me (does it have eyes?). I have a lot of feather duster worms; I love them!

I looked up the Peanut worm and it is not very handsome. Reminds me a tiny bit of a slug but the Feather Duster worm is a real eye catcher. I saw one of those (I think) at the pet store. I first thought it was some kind of coral before I noticed it moving then I thought it as an anemone. I would have to look again just to see. I think that means another trip to the pet store ;) We don't have any "real" aquarium stores around here :( I would most likely have to go to the big city to find one. A salt water tank would be fun to have but not something that I want to tackle as I bet they take tons of time to get the environment correct. Sounds like your really enjoying yours.

Tia, corals do move! They are normally affixed to whatever they are on but they open and close. My xenia opens and closes almost constantly. They're also called pulsing corals. If I touch my feather duster worms or corals, they close up. Or, sometimes I just have to look at them, and they close up. I know they don't have eyes but those worms know I'm there!

Corals move??? Well, I'll be! Never knew that! I always thought they were attached to something and stationary.

They are attached but that doesn't mean they can't move. Maybe you're defining move as change location while I'm defining it as any movement. It doesn't matter though because a few corals actually can get up, and over time, change location (not fast though).
