Hi,
I have 36 fully cycled tank. Parameters are ph - 8, ammonia - 0, nitrite - 0, nitrate - 1. I have a clownfish, firefish, 2 snails, and three hermit crabs. Just now i noticed my clownfish swimming eratically (swimming against the glass and top to bottom). Now he is swimming at the very bottom of the tank almost sitting by the sand. Im really worry about him since i know this is not typical behavior. He has been eating fine (i feed my fish twice a day small portions of snl pellets). Yesterday, i started feeding him rods food that is the only thing i changed from my tank. Also, he has always had a SINGLE white spot by his gills. Ive showed people pictures and nobody seems to think it was anything serious. Please any help will be greatly appreciated. Pics of tge white spot can be seen in the pictures.
