Hello, Reefers! I have a Neon Green Cabbage Coral that I have had on an island for about 2 years. I haven't seen it spread, but it gets bigger and bigger. On my main rockwork, I ONLY do non-encrusting corals/ NO Fast spreading soft corals. My question is, could I move this Neon Green Cabbage Coral to my main rock work or will this spread and begin to take over, like a xenia/zoa/GSP???
