Be good for a grow out tank for RBP's till they reach about 3". Then you will really need to upgrade to a 90g or larger. Althought they state you need 20g per RBP, I always like giving my fish more room.
As for the solo Piranha's they all grow to 12" or better. So its better to just get a larger tank to start with.
But yeah 30 gallon is a guppy tank, or a good tank for Shelldweller Cichlids. Not Piranha.
