I wouldn't recommend sand if you have a young beardie. They tend to ingest it which causes impaction. Sand also is a lot harder to keep clean and bacteria-free. I would suggest getting some slate tiles or using indoor/outdoor carpet (without loops). Those are all money saving as well.
The answer to your question: Washed and sifted children's play sand.
Some advice: Don't use it. Any particulate substrate has a very high chance of causing impaction in your beardie, especially in juvenile beardies. You should consider using tiles, reptile carpet, non-adhesive shelf liner, paper towels, unprinted newspaper, anything but sand....
Currently trying not to stress over my anemic dragon....she is being treated, but I don't agree with her treatment plan and have been seeking out a second opinion from another vet. If anyone else has dealt with anemia, please let me know how it was resolved. I am losing sleep over this
Another post lol. My beardie does not like enclosures. Her tank is the kids room and she has created a nesting/bed spot in the corner. She will cuddle with my son but she know when the lights are out and the kids go to sleep, she literally goes to her bed like she is our 3rd baby. I love her. And to think, I never wanted a beardie lol
Please help. My beardie is my baby and I am worried she may be egg bound but I can't tell. She is over 2 yrs old and has never laid an egg. She has been swollen for two days and can't tell if she may be impacted or egg bound. Please help.
