allright well i finally got my LR tonight and got it into my tank. I found an interesting little hitchhiker hiding in one of the crevices. i tried to take a pic but camera no good that close. its about as big around as a dime cant tell on the color, but it has translucent tentacles. kinda looks like a large polyp of some kind. will try to get a pic. any ideas
