I have a dozen small terracotta pots lying around and I want to put them in my aquarium. Not all of htem. Just a few. My fish (I just bought today) don't have any real shelter other then my plants. I just want to know if it's safe to add them or do I need to test them first? I've just poured boiling water over them to kill anything that might be on them. Do I need to do anythign else?
Thanks
