What are these?

Okay I owe you all an apology. especially to Maintenance man.
I apologize for for blasting and ranting.
It was not meant to be directed at anybody in particular. I guess I've seen to many threads with incorrect info.
I think BC_GRl asked a good question, and deserves a good answer. (I liked DJ88's)
Yes I like the socializing as well(in the threads). I guess I just had a rude way of venting, my wrong.

To anyone that will now "watch" me for slip ups, I am not "hollier than thou". I make many mistakes, but I put allot of effort into avoiding them.
Believe it or not I spend most of my time listening.

By the way Tony,
I crack up every time I see your signature qoute.

Peace?

Van, the items I asked about were not ones we've purchased and put the on the rock to attach, but rather they were what was already on live rock that we had purchased. So, they came free and we just wanted to know what it was.

Nice hitchhikers, must have been nice rock. Too many boulders in the trade these days it's nice to see stowaways.
