I have an oddity in my tank. I have tried to get pictures but he is to deep in the tank to focus on and the rock is lower in the tank so I can't pull it close to the front for a pic. I belive he is a clam. It looks like a piece of the rock it is on but it opens just a little it has what appear to be brisles sticking out of the sides and is greenish inside, he also has a hard tube like structure gowing beside him that is about an inch tall, he is about the size and shape of a penny if you set on railroad tracks and he does respond to light, water movement and touch by closing. I have never had clams or any shellfish and have only noticed him in the last month. Any ideas other then post a pic?
