How teritorial are green frilly mushrooms?

[easygoer2]

I have alot of these, some about 4" in diamiter spreading all over my tank. Also the same problem with Blue tunga shroons. How do I get these under control? Are these teritorial?

As for "Territorial" they do pack a whallop (strong nematocysts deliver a harsh sting) and will kill many other corals that they come into physical contact with. Here is a link to a thread that may be interesting to you:

It shows a couple of photos of my ricordea killing tissue on a montipora colony.

I SOLD SOME BROWN FRILLY MUSHES THAT STUNG MY FOREARM .
ALL MUSHROOMS CAN BE AGGRESIVE I'VE LAST VARIOUS HARD CORALS
OVER THE YEARS SO I SOLD THEM ALL .ACCEPT FOR FOUR LARGE
RICODEA ABOUT 8" ACROSS. I HAD TO TEAR SOME OF THESE IN HALF
TO REMOVE THE ROCKS THEY HAD COLONISED. IF YOU LOOK AT THE
BASES THEY JUST LEAVE SMALL PIECES THAT GROW INTO MINITURES.
AS FOR AGGRESION LOOK ALONGE THE EDGES CLOSEST TO ANY CORAL
AND YOU SHOULD FIND THE TENTACLES EXSPANDED READY FOR WAR.
THE LARGE SPECIES LOOK GREAT BUT STILL SPREAD.THE BEST I FOUND WAS TO SITE THE ROCK THEY WERE ON OUT IN THE OPEN
SAND.
