I have a 15 gallon column tank with two clownfish, watchmen goby, peppermint shrimp, and pistol shrimp. I have had the clownfish for about a month and they have been doing well until today. The smaller of the two clownfish has a black "pimple or wart" like bulge on his abdomen. The bulge appeared overnight. I took my water to get tested yesterday and the nitrate and nitrite levels were slightly elevated so I did a 1 gallon water change and will do another on friday. Does anyone know what this black bulge might be??
