Aqua Natural river pebbles are sourced from New Zealand rivers and streams that have tumbled the pebble over long periods of time resulting in smooth rounded stone that cannot cause injury or cuts in any way.
Smooth river pebbles are the substrate of choice for both freshwater turtles and axolotls. Both turtles and axolotls tend to lunge at thier food and prey, this form of behaviour can result in unwated ingestion of substrate which can cause impaction and internal bleeding. This causes severe injury or death. Using smooth pebbles ensures your animals cannot swallow them by mistake.
Unlike sand and gravel, Aqua Natural pebbles are easy to remove and clean when needed. Algae and other debris can be scrubbed off easily, and the spaces in between allow for easier access to pick up waste with a siphon.
