Seashells for aquarium?

[Kapachuka3]

Ive put some seashells in my tank and my urchin really likes them and my clown sometimes throws them around with his tail. Im looking to add a few more into the tank. They’ve been out of the ocean now for several years, the ones I’ve added are fine and were also out of the ocean for a long while. Would they be fine to add?

Should be fine. May want to make sure they are clean. But otherwise fine.

Agreed. Just rinse them off to clean them up a bit, but I don’t see any other issues.
