In my tank after my file fish got a taste for them and cleared out every polyp in my display. I just thought this smalle Box from reefing art that I found at my local fish store. Really well made acrylic with a magnet on the front I now have a place to keep a beautiful Zoa garden away from my file fish I suspect that they will grow all of the Box making this a great addition to my tank
