I’m onto my second pair of clownfish after my first pair of mochas died. Now my second pair of clowns don’t look good. One has already died after I moved them both to a quarantine tank and the other has labored breathing laying on its side and hardly moving. The tank stays between 76 and 77 degrees. Ammonia is 0 nitrites are low (0.25 ppm max) but not completely zeroed out. Nitrates are around 5-10 ppm and ph is about 8.2. I have several mushrooms, a couple leathers, a pipe organ, a candy cane, and a Duncan all doing very well. There’s also a jawfish, a blenny, a cardinal, and a dozen or so snails and hermits also all doing well. The tank is 30 gallons and I added an aerator to make sure that wasn’t the problem after the last ones died. Everything else looks fine no labored breathing or anything like that. The only new addition recently was a bubble top anemone. Any thoughts on what is causing my clowns to die? Both sets lasted about 10 days before showing any signs of issues
