Mama shrimp gave birth to mini shrimps

Yeah! I've got mini shrimps now! They are really small and difficult to find. I was actually searching for my snail when I saw those tiny ones. So happy!!! Of course the sad thing is, another is gone. It's hiding in the bushes and not moving so I reckon it's dead. Worst of all, there are lots of odd looking worms in all shapes and sizes in the tank. I think Coco, my water slug, brought friends. Though not alot, I cannot guarantee that they won't grow. Hope they don't harm my shrimps coz I don't know how to get rid of 'em worms :p
