grows like my orange and purple cap thanks John
Phyl said:What I can see there looks a lot like a galaxea. Does it look like the coral in that link to you? If it is Galaxea, it doesn't really grow like a cap (plating), but more of an encrusting (like Hydnophora). Galaxea is an aggressive stinging coral that needs lots of room for it's nightly escapades where the stingers come out in long sweeping strings that sting anything nearby.
Or a New Year's Eve hat. It could be either. ;D
