So I had two clownfish, the one depicted just died. The first clowns symptoms were as follows. Pale skin, lethargy, and bright red gills. Water parameters were all fine after all testing. The black clown below was displaying no signs of distress. I preformed a 50% water change and unfortunately the clown died. Fast forward three weeks later to today and the same thing has happened. I preformed another 50 percent water change after testing due to my nitrates being 3ppm( usually 0). I have included photos of this guy up close to see if anyone would recognize any diseases. Really at a loss here. I have kept fish for years and never had this issue. Want to make sure I’m not missing anything before adding new fish.
