This stuff just starting growing.....

Out of no where, this grass like stuff started growing. My fox face loves lying in it..

 

Looks like GSP (green star polyps), just make sure they don't run wild on you.

 

GSP and in the right conditions can take the tank over.

Mine started from a little spot on a rock to this in a year but I like it. It's got its own corner.

 

Very impressive

 

Thank you. It's very aggressive though so I'm in the process of redoing my tank and it's gonna be by itself so it can't spread to other rocks. It will kill any coral in its path so OP be careful

 

Try putting one of the hammer corals in front of it. They will nuke the GSP like it's nothing but won't kill it. I've had one hammer taking on a hydnophora and winning. Even just use them as a perimeter to keep it from going any further. Must be sweeper tentacles at night killing the GSP. GSP is very hard to kill. I don't even think you could kill it with all 4 placed on it.

found this online

""It has completely taken over the back wall and overflow in my aquarium. I have multiple frogspawns and hammers and that seems to keep it off of the other rocks like a do not cross barricade. The aquarium is in my office so I am letting the best coral win the competition for space.""

 

I actually had to move my euphyllia because the GSP killed a head of my hammer. Maybe mine is just aggressive but my euphyllia and other LPS have lost a battle against it.

 

Great coral to frag though...
