Pebbles of any kind are bad news in an aquarium containing fish. They provide places for uneaten food and bits of poo and rubbish to hide. These then go rotten and can not be removed without major problems. Most successfull fish keepers have either a bare base (muck is easily seen and removed with a syphon) or they use a fairly fine gravel as a base in which to grow water plants. (Gravel can still be cleaned easily with a syphon).
In a bowl with water, plants and pebbles.
To effectively use clay pebbles for succulents in your garden, first ensure the pebbles are clean and have good drainage. Place a layer of pebbles at the bottom of the pot before adding soil to improve aeration and prevent waterlogging. When watering, allow excess water to drain out to prevent root rot. Monitor the moisture levels in the soil to avoid overwatering.

Water passes through pebbles because they have larger gaps between them, allowing water to flow through. Clay, on the other hand, has smaller gaps between its particles, making it less permeable to water. This results in water being unable to pass through the clay surface easily.
Most people would keep goldfish in a bowl or tank, filled with water. You can always add scenery such as pebbles plants and castles :D
Sand settles faster than pebbles and clay. Sand particles have smaller size and lower density, allowing them to quickly compact and settle in a sedimentation process. Pebbles are larger and denser, while clay particles are very fine and may take longer to settle due to their tendency to remain suspended in water.
George Peacock used usual household items such as silverware, clay, rocks and pebbles, and knotted cloths.
They aren't really eating the pebbles, they are looking for food. Goldfish are scavengers and will eat anything they can find. Once they know it's not edible they will spit it out.

Heating clay pebbles in a microwave can be risky as they may crack or explode due to uneven heat distribution. It's safer to heat them in an oven following manufacturer's instructions. Ensure that the pebbles are completely cool before using them in a weighted blanket for dogs.
DO NOT USE PEBBLES!!!!!!!!!! Use newspaper or the bedding in pet stores for rodents. DO NOT USE PEBBLES!!!! THEY ARE A BIG NO-NO FOR RODENTS!!!!
You would typically find particles of clay with no sand or pebbles in areas where the clay has been deposited and settled without the presence of other materials. This can occur in lakes, ponds, or slow-moving rivers where only the finest particles are able to settle out. Clay beds and formations in underground geologic layers are also good sources of pure clay.
