I have a 90 gallon reef tank and it's going pretty well. It has an anemone that was only about 4 inches across a year ago. it's now 8-12inches across maybe even a little bigger, and every now and then brushes a zoa colony and nicks my clam every now and then. Is it too? I've got a pair of maroon clown fish that host in it but I'm worried about my other smaller fish and my corals that are growing more and more.
