Not recommended. Will perform a nitrate sync and is too coarse and sharp for burrowing fish or invertebrates.

For decoration on a bare bottom tank, where it can be removed, cleaned and replaced, might work.

Not alone. I have mixed a small amount of it into my sand for my pistol shrimp and goby to use for their burrow.

Pro:
When paired with other substrate - Good structure for burrowers to make a burrow

Cons:
could be sharp and can cut fish (mainly diggers)
can easily trap food when used alone
