sera Rock Gray Pebble

Round river stones

  • dark gray, well rounded natural stones with a slightly porous structure
  • ideal for creating river landscapes but also minimalist layouts using a few large stones
  • the surface provides a settling area for periphyton as natural food for hillstream loaches and other animals that feed on periphyton such as shrimps
  • the combination with moss perfectly adds to the beauty of the stones
  • available in three different sizes


The Gray Pebbles are ideal for anyone who wants to create a calm, harmonious, Zen-style layout in their aquarium. When combined with roots and plants that prefer flowing water, they also add natural highlights to recreate a river landscape. In addition to their decorative purpose, stones in aquariums also play an important role in the appropriate keeping of various animals. Due to the special surface of the Gray Pebbles, biofilms and periphyton easily develop on them. These are a necessary source of nutrition for fish, such as hillstream loaches, and invertebrates.
