Patrick,

Chances are it's laying somewhere on the sand in your tank. One piece of mine kept getting knocked over by different critters until I really jammed the piece into a hole.

Once it finally attached itself to the rock, no problems since.

But I did find the small piece in different places in my tank for the first couple days. Keep looking it will surface I'm sure. And as long as it gets a bit of light, it will continue to grow wherever it's lying.

I don't know of anything that will chomp on Colt, except maybe a rogue shrimp or crab?
