Mysterious Creature...........

[turtle]

Last night when I fed my fish I saw a strange creature come out and crab a chunk of food. It was completely black and looked like a snake with legs. It kind of freaked me out. Anyone have any idea what this might be? I hope it is not going to ruin my beautiful tank. Your thoughts........
Thanks,

Well, I saw this mysterious thing again. It was really really shy to come out of the rocks. It hides underneath my LR and is black. It almost looks like a centipede with short antenas on top of its head. It also has tiny legs like a shrimp underneath it's body. It also has 2 pinchers at the front of its jaw (kind of like an ant) that it eats with. It went after a piece of mysis shrimp and formula 1. It also is lightning fast. It came out to grab a piece of food and bolted back once it saw me. Does that help at all? Any thoughts?
