Natural Quartz not only looks wonderful but has also been shown to help reduce the build up of algae in the aquarium. This is partly due to the huge surface area of quartz which offers added space for the establishment of ‘tank cleaning’ bacteria.
Quartz sparkles underwater due to the many light reflecting facets and looks like diamonds have been added to your tank.
I would definitely recommend adding these little guys to your tank. They are very playful and entertaining. My three were very healthy and quickly adjusted to my tank.
