Rocks
I added them in a lottery mix of powder blue, orange, and dairy cow isopods. Look nice inside their enclosure.

Very small
I got these to help with the low ph on my tank. They are so small they have no affect.

Isopods Love Them
Perfect size for my isopods, I use the rocks to give them calcium. The rocks last a lot longer than the cuttlebone I was buying. The rocks in the long run are cheaper than the cuttlebones I was buying.

Not worth the money
Description says 6 rocks. I got 5 marble sized pieces. Very disappointing.
