We know pretty well what matter is and how it interacts with the others.

Dark matter interacts through gravity but not light. Beyond that I haven't heard much else.

And lastly anti-matter has an opposite charge and interacts with matter through annihilation. I think I remember hearing that it would react with dark matter the same way.

So my question is, does anti-dark matter exist, and what are it's properties?

To my understanding, dark matter and dark energy is just a placeholder name for things we can see evidence of via influence on other things, but we don't actually know what they are exactly. It could be a multitude of things, not just one.
