Ok...the rock itself isn't alive...when we talk about LR
it is the bacteria and other critters on and in the rock that is alive and makes it LR
. Yes what are you are seeing is a very good thing. The little "bugs" are pods
..most likely amphipods...that is a good sign. All those worms and other critters are usually a good thing. Some hitchikers are not so good be we can worry about that later. As for the red starfish, we will need a pic to help you out there.
You should be excited! I know I was...when I started my tank I had 1 rock and a lot of sand and water. I would sit and look at that 1 rock for ever. Don't always believe everything the LFS
tells you. Ask questions and if you aren't sure of the answers you get there come here and repeat them. We don't get paid and aren't going to pull your leg.
Get those pics! We do love them!!
