Not only will you find the Live Rock great for your tank's health, but the life that comes from it
is incredible! As your tank ages & the conditions become right, you will find all kinds of creatures inhabiting your tank! Feather dusters, pods, stomella's, and lots more. I am setting up a 30 gc with about 45 lbs. of LR, and have 2 small starfish crawling around now. On the flip side, the rock also contains life that is NOT good for your tank, Mantis Shrimp, Zoanthid Eating Nudibranches, Sea Spiders etc. Another creature that comes with live rock are Bristle Worms. There is debate on these being good or bad for a tank. Mostly, I think it depends on what you stock your tank with so do some research. I leave mine in the tank. They are NOT good to human fingers if touched, the bristles can be painful. I would advise that when you handle your LR, wear gloves to prevent getting bitten or stung by a number of dangerous sea life. The Mantis Shrimp are nicknamed "thumb splitters" which should give you an indication of why "handling with care" is important. Also watch out for Aiptasia that comes with LR. This is a pest anemone that can reproduce rapidly, take over a tank, and even sting some corals and fishes. Most of the LR life comes out at night so you'll want to invest in a good flashlight and lots of batteries too, lol! I've set an alarm to get up at 2-3am several times to check out my tank!

It's moving day today, my new 30 gc Reef has cycled and all the creatures, except the Sebae Anemone, in my 10 gc nano will be moved. The new tank is not established enough for the SA,
that will be 2-3 months (at least) down the road.
