Hello I am a brand new Saltwater Hobbyist and currently have a 150 gallon FOWLR saltwater tank that has been running for a month now. I am at a loss. My tank has cycled and all the parameters are where they need to be (Salinity-1.025, 0ppm Ammonia, 8.0-PH, 0ppm Nitrite) and currently have 2 clownfish, a tiny yellow belly regal tang, 2 bengai Cardinalfish, a royal gramma, an African Red Knob Starfish, and some hermit crabs for cleanup. I have ordered larger fish (A latticed butterflyfish, coral beauty, and Powder brown Tang) but all 3 have died within 2 days. I don’t understand why. None have black or white ich, or any other marine skin condition that I could see. For food, I feed them frozen foods such as Mysis Shrimp, Mega Marine, and Algae Based marine food. Please help.
