Great size to finish off your aquascape with some rubble if you’ve already set up with large LifeRock pieces. Great size to attach frags to as well and make “islands” for quick spreading corals like Xenia, zoas, etc. Note that they aren’t all consistent in coloring and intensity of purple. I personally think that makes it a bit more natural, but important to know if you’re expecting consistent color on all the pieces. My box had half of the rocks with a significantly lighter shade of purple.

Comes with a pretty good amount in the box, the coloring isn’t on the rocks very good though and you need to buy at least 8 boxes for a 90 gallon tank
