It is a real aragonitic rock with extensive macro and micro-porosity infused with spored bacteria. It is safe for all fish and inverts and best suited for use in marine and reef aquariums. LifeRock can be purchased in many shapes and sizes, with the Nano Arch being the newest addition to the series.

Directions for Use:

Please Note: Each box will contain a variety of rocks of different sizes and shapes. We are unable to take any special requests for rocks of a particular dimension or size. Because of the fragile nature of this rock, it is possible for the rock to break during shipment. We do our best to package the rock sufficiently to minimize damages. As UPS does not consider this item insurable, we are unable to replace or refund damaged pieces.

It is possible to attach multiple pieces together using aquarium epoxy in order to make large shelves or repair damaged rock.

No, I would not recommend this.

Color flakes off rocks after 2 months

Pros: None

Cons: Color comes off

The color flake off the rocks after 2 months. I started a new 20 gallon tank with this rock and it looked great for about a month then I noticed the color coming off a little but now it's been 2 months and it started to get bad I glued my entire area scape to be one Structure so I can't even swap it out now Would definitely not recommend this
