What would you like to know. I have it in both my tanks. It can be invasive once it gets established it spreads like crazy. It can be controlled though by removing it and is easily fragged into other colonies by placing a rock next to it and having it spread onto the rock beside it. I have it growing up the side of my 29g and it moves around to where it wants to be which isn't always what you would want. It is interesting, I love to watch it as it moves a lot and is constantly pulsing each polyp on it's own schedule not all at once, so it appears to be moving.
