Amatuer Footage: Creatures of the night

If you've gone night diving you'd know that life in the sea takes on a new form when night falls and same goes for the deep blue sea in my HDB.

Resolution is not very clear but if you watch the sand bed closely, you'd realise that it comes alive with bugs scrambling here and there and there's a mysterious slug on the glass wall. Never knew it existed. I've got better footage but youtube wouldn't let me upload it cos its too big. Bister worms and sleeping clown fishes. In the following episode of this nocturnal video series i guess.
