Hello, fairly new to marine tanks, looking for some advice on what the white things on my clownfish could be? Its a wild clownfish. No heavy breathing or loss of appetite. Other tankmates include clarkii clown and 2 chromis. Showing no symptoms. Tank Size 100 gallons. Ammonia=0 Nitrite=0 Nitrate=10ppm Tank has been running a few months now. Doesn't appear as speckled as white spot would be, he's had it for about a week now. I believe brook is a fairly fast killer so not sure it is that. Any advice appreciated.
