???should i be worried that my oranda has a few missing scales ,,i tested my water and the no3 was quite high so i did a 20% wc,,i do wc every week and use a pince of aqua salt,,my oranda(chubby) is behaving normal,,eating ok and pooing ok and my other fish are fine,,when i done the partial wc today i added melafix and salt,,should i be worried about this,,she is my pride and joy
