Yea, I wouldnt use them on anything in my home, But if it was at a place of business where my customers were #1 on my list and not the maintenance on my tanks the fake corals would be the way to go.
Thats my theory, I got one as a hitchhiker on a piece of coral and Im glad its in there. If you dont want the "worm filled ngihtmares" dont watch them.
tank is sittin in the dining room waiting for me to over come my valentines spending lol Im looking to pick up around 8-10lbs of Lr in the next couple of days then itll be time to get it wet and start cycling it.
