I'm probably in the wrong thread, but I have the weirdest thing ever. I live in Southern Utah but your board is more active and every time I see a picture or article in my world wide web travels I see Adam Blundell's name. So I know the reefers in the know are right here!

So I bought this rock that had a bunch of striped green mushroom on it but I have 2 12 gallon nanos and my neighbor has a few tanks as well. The rock was WAYYY too big for a nano, so i cracked it up and spread it out. The first weird thing came as I split the rock. There was a weird little white bivalve that was living in the center of the rock and it had built a tube so it could filter feed but it was completely encased and still alive. I asked everyone around here that I know about it and no one had a clue as to what it was. I started searching and it sounded much like the bivalved snail but I never saw a picture of one that was pure white. I was trying to decide where to take it because it seemed a bit rare and I wanted it to go to someone more smarticle than me

It was thriving then one day either my maroon clown or my damsel ate it. Then one day I noticed this big fat white worm floating around in the tank and on one end it had these iridescent filaments on one end. I saw it the one day but not since. However on one of the rocks that has the green shrooms I can see these fringes of fine iridescent filament coming from INSIDE the rock. There's no holes that I can see that it would go in and out of, but it looks so similar to the strands on the worm that I can't help but think that is what is in the rock. I can't get a picture to show you because it's so fine and you have to move around to capture the iridescence. I haven't touched them but they aren't pliable. They seem stiff. What do you guys think?
I think this rock is like the OLD boxes of Cracker Jacks when you opened the box the prizes were actually cool.
Sorry if I'm in the wrong place and TIA,
Briar.
