Recently had on from live rock, other lived in center of a soft coral, never seen that. The one in coral, looks white and like the Abominable Snowman on steroids. Abominable Snowman in a separate chamber in sump, so ok. Other in DT. No issuesGot some live rock for my refugium and this guy dropped out when I was moving it. Type? Good? Bad?? What do I do with him?
