I'm in need of a little help/advice with a simulation/game that I'm working on.

Basically, with the simulation, you're a scientist that discovered a new life form. You must contain these lifeforms and provide their needs as they multiply and evolve.

I need help with a few things.

1) I'm using the image control to display the creatures. I'm trying to find a better way to make them move around within their tank and such so they don't all group up in the same spot. Also when there's so many of them (see #2), it runs really slow because I'm using a For statement.

2) I need a better way to come up with how they multiply. Right now it just doubles everytime the counter is run. I need a way so that there's only 2 or 3 each time it goes around, and gets slightly higher depending on the population.

Please take a look at the project and see if you can provide any assistance or suggestions. Thanks
