saw a worm after the white lights went out. i flickered them real quick to try to get a better look and he moved back a bit. did a search on hitchhiker FAQ and it didn't look like any of those worms, except maybe a feather duster without the duster! he's just small and white. i only saw 2in maybe of him and didn't see if there was a hole right there. he's gone now. oh well. i'm kind of a record keeper. this live rock has brought things i don't know about to my tank. it's exciting, but i sure would like to know about all of it! :) and the sea star is done eatting and finally back in the water -- a short 5 hours later. wow. what a lunch break! :) and he's back at eatting algae it seems. what a fat pig.
