Out of curiosity, what are those blue things back there near the mushroom? Is it some kind of sponge?
Actually, That is just a decorative painted coral skeleton that I bought several years ago when I started my first FO marine tank. Dont ask me what they painted it with but the color has held up well over the years and is obviously reef safe. That deep blue color always peaks peoples curiosity, you are not the first to ask.
