Enjoy your year or two with her.
Looks like an O. vulgaris. Longest lifespan in captivity from settlement I've seen was just about 25 months. In general, 12-15 months (especially for females).
Really awesome for the time they're around...But, don't expect your tank's rock work to stay how it is now. She's getting around the size they start demolishing and building. Also, I hope your tank is about as hermetically sealed as it can be. They are only limited by the size of their beak in the space they can pass through.....and they will find that space.
