Went over to Daniel's place last night and he had an interesting pink something or another on a plug. Looking at it, it looks exactly like something that a buddy of mine shot while at a public aquarium. Anyone know the heck it is? (I thought it was a sponge of some kind or another, but it's hard like an SPS...)
Width of the branch was around 1/8".
