One Becomes Two

We have teeny tiny starfish crawling all over the glass of our fish tank. We started out with a few and over time they invaded. They are only as big as the diameter of a pink eraser on the end of a pencil. We've always wondered how they multiplied so quickly. I finally caught one becoming two the other day. They just split right in half and grow more legs.

The picture above and the one below are not of the same starfish. They don't change rapidly enough to even see any movement. It seems they know to keep still until we are not looking. This picture below even shows it's tiny feelers as it is dividing. On the lower left of the picture there is a white dot. That's a baby snail. I didn't even see it when I took the picture until I blew it up. The starfish look really spongy but are very crusty and hard.

These are our clown fish. Of course the large one is named Marlin and the smaller is Nemo. I was doing some reading and discovered the largest clown in the group is always the female. The rest are all males. If the female dies then the largest of the remaining males becomes the new female. Ooooh, Aaaah!

These are some of the rest of our fish. We have a scopas tang, the largest one here, a blue hippo tang (Dorie of course). We have some other interesting fish and creatures but they never stop moving and getting a picture is nearly impossible without it being too blurry.
