Limestone Rock
Our premium limestone is not only a great calcium source but also offers environmental enrichment for your isopods. Hand-picked and cleaned, the Ontario Invert Farm offers only the best limestone slabs, ensuring pieces offered are both lightweight and concave. This provides an effective hide for your isopods and other terrarium inhabitants. 
If a piece is too large, these rocks are easy to break apart with a light tap from a hammer and make the perfect size. Calcium dependant animals such as snails and isopods are able to use the calcium-rich limestone as a supplementary source of calcium, in addition to its use as a hide.
