Something freaky driving me crazy... - Frag Outpost Forums - Coral Propagation and Reef Aquarium Forums

All right, I think I'm either losing my mind or something is seriously up with my tank. Every night at about the same time (10-11pm) while I sit and watch TV, I start hearing this scratching sound coming from my tank. It sounds like this grinding/scratching kinda noise. Whenever I look in the tank with a flashlight, I see nothing. I have always suspected some hidden critter in my tank since day one. When I first set up the 60g hex I would, almost daily, see long strips of what looked like fecal material collecting in a corner of the tank. After moving to the new tank, I found one again. Now I'm hearing all this scratching. Can anyone give me a clue as to what they think it might be? Here's some pictures of the pooh from the first tank:

have you tried waiting until the lights have been off for a few hours and then checking with a flashlight that is crazy about the scratching noise I have never heard anything like that before

When I hear it, the lights have been out for two hours or so. I have a blue LED for moonlight on the new tank. The lights in the room are still on, as well as the TV.

How would you describ the scratching sound?

My initial impression would be something scratching on the glass. The only thing I know of in the tank that could do that would be my trochus snails, maybe doing a 180 on the glass, but I doubt that's it.

any other sounds like clicking or knocking?

that must be a giant snail to leave a piece of poop that big
