Last Friday before water change he had about 6 white dots on him, overnight after water change they disappeared. My little man has been acting a bit strange and he stopped blowing bubbles for me :(
According to my test strips the water quality is fine even though I think I put a bit to much of the biological filter aid in the tank and it gets a bit scummy on the surface and in the filter/pump chamber!
Anyway when i got home tonight I found he had suffered another breakout in and around his tail and fins (pic below) this is not like last week, last week they were on his head and body and slightly bigger than this. Please help me diagnose him? He's my first tropical fish and I dont want to fail! :(
