Hi Guys, have noticed today a small growth/pimple on side of my blue tang. There are also 2 small white marks on his side fin that you can see in the video. The mark on his body shows white in the video but its definitely not. Any idea?? Also noticed ot was swimming past some rocks on its side kinda like he was scratching. Still eating well and swimming as normal. All other fish show no signs of anything and all looking great.
