The last hitchhiking peanut worm has died.

My live rock is still "live" though: the coralline algae on the front side of the rock has really colored up within the last week. It was very brightly colored on the back side of the rock, but sort of dull-looking on the front side when I got the rock.
It's goin' crazy now.
You can see a pic of my picoreef rock by clicking the nanoreef link in my sig.
Something I'm wondering about...I've seen this stuff called "Purple Up" which is supposed to encourage the growth of coralline algae. My algae is gorgeous (the pic doesn't do it justice!), so I'm wondering if I should get some to "feed" the coralline algae. Since my little biotope is basically just a "pet rock" now that the hitchhikers are gone, the brilliantly colored rock is the star of the tank. :-)
