Aquael basalt gravel 2 - 4 mm

Basalt gravel in the grain size 2 - 4 mm.

Very nice and pure basalt gravel, which is water neutral and has a beautiful dark coloration.

Basalt is very suitable for all species of Neocaridinas, which usually show more beautiful colors on dark substrate, but also for fighting fish or other fish species that feel more comfortable with dark substrate.
