My blue hippo tang starting flashing and I attempted to dose with metaflex after talking with FS. The next morning I notice it was having trouble swimming. Shortly after it died. Looking for help on what people think it could have been. Water parameters are in picture below. All other fish seem fine. Thanks for the feedback. Trying to learn how to prevent this again.I had him for about month and was eating appear to be healthy until the last couple days.
