Product Description
The sera Rock Hole Stone is a classic hole rock, especially popular in African-themed freshwater aquariums such as Lake Malawi and Lake Tanganyika setups. Its distinctive holey structure features numerous cavities and furrows, providing excellent shelter for fish, shrimp, and crayfish, while also offering ideal surfaces for plant attachment.
Due to its natural lime content, the rock may slightly increase water hardness and carbonate hardness (KH). Regular monitoring of KH is recommended, with partial water changes carried out if adjustments are needed.
As this is a natural product, each stone is unique and may vary in shape, size, and colour from the images shown.
