This is my first freshwater tank, I added 5 glowlight tetras to my tank and its day 6 and I started noticing some of the fins are milky in small parts, I dont know what it is. I think it might be ich but Im not sure I have been testing the water and the quality is good. the temperature has been changing a bit from about 75 to about 81 throughout the day to night. I added some stress coat to the water. Does anyone know what this is and what is causing it? + how can I treat it?
Sorry for the blurry images, look at the white area on the fin
