My question is what should I look for what killed 4 tangs in a week. One by one they would die they ate till their last day. They showed no signs of stress. In a 24 hr. period I noticed that they would always go into the return area in the tank where the flow was the strongest before they die. My last tang did not have any spots at all no discoloration at all. I have 2 maroon clowns, 4 green chromis, yellowhead goby. I have 125 reef tank. Everything else is fine.
