Help needed:
I have had a 70 gallon saltwater tank set up for a year. My invertebrates (snails, hermit crabs and fire shrimp do just fine. Anytime I try to add fish they die within 2-3 weeks. Water samples taken in to store where fish are bought show levels are correct including salt. I have sent out water twice to have chemical/metal levels checked and those results come back good. The tank has crushed coral, live and dead coral rocks. Does anyone have an idea of why the fish won’t survive. I have lost over 20.
