Is 'Bacardi Reserva Anejo Especial' the same as 'Bacardi Anejo'?

I purchased a bottle of Westerhall Plantation several years ago and have been saving some of it. Batch 1512. I also bought some more last week - found 1 bottle in a sales bin. When I got it home it had the same problem. Both bottles have 'dust-like' material floating in them. The old bottle did not have this when I first got it. I would not expect anything to grow in rum? Any idea what it is?
