I am fairly new to the hobby like I said before and yesterday I added some calcium to my tank and this morning I woke up and checked the tank out and my tang has white dots on his body. Can it be the calcium cause the same white dots are on my glass?
Also I woke up earlier then usual and my tangs did not seem as active. The tangs seemed to stay in one spot as if it were still asleep. Could it be that they are use to a sleeping schedule and were still asleep or lazy? I usually don't turn their light on until 2pm because I work night shift so they have been use to my schedule maybe. Any help please!!!
