After a 25 gallon water change in which I vacuumed the sand bed I let the waste water stand and pumped off all but about 2 cups of water and took a drop of it and put on a slide. I may never put my hand in the tank again. 
Put this here to see if any of the smaller critters might be dinos.
From 0:00 to 0:06 what's the worm like thing and the snake thing in the upper left corner.
From 0:07 to 0:40 what's the tiny lightening fast critters?
At 0:43 what's the thing that looks like two sperm butting heads?
From 0:52 to 1:06 big ugly thing with two legs coming out of what looks like a mouth?
From 1:06 to the end . whats the big clear thing left lower corner, another of the fast things at 250x and the immobile thing that looks like a snail shell?
