You will receive either 20 or 40 casuarina cones. These cones are very similar to Alder Cones and Indian Almond Leaves and act in a similar way. The cones are beneficial to shrimp, bettas, Apistogrammas and Corydoras species for their healing properties and ability to lower the pH.
Added a nice touch to my tanks
Cones were as advertised and great shape. Too early for me to say how effective they are in shrimp keeping but the shrimp did investigate them after i put them in.
