Hello, I recently added a few shell dwellers in my african cichlid tank and I was wondering if I can add some seashells in my tank. I live on Long island, NY and I frequently find giant conch shells washed up on the beach. They seem to be perfect breeding shells for my cichlids and I was wondering if it would be safe to put in my tank. I know trace amounts of marine salt is overall good for the health of the fish, but should I take any precautions before adding these to my tank? thanx in advance.:headbang2:
