Anybody know what this could be? Looks like an empty coconut to me, but no really sure. Any ideas?

Sweet, thanks AlgeHatr.

Anybody ever try this with their aquarium, and if so what were the effects on the water?

Coconut shells are safe to use as breeding caves as long as all the white fruit (meat) has been removed.

Ancistris cats love grazing on the husk fibers and shell
