Hi Poopoochee,
Sand, plants and other ornament to your triops can be used on your aquarium once they're fully grown. Consider too, some ornamentals may change the pH as well as the quality of water of your triops tank, thus caution is highly adviced.
For other related information, please visit and talk to our Pet Care Consultants in all our PLC outlets.
Warm regards,
Eliezer M. Bauzon, DVM RN
