so its been a couple weeks since i noticed the very small white spots on my tangs fins.. they were very very small now about 2 weeks later the spot have grown pretty big. i was told that good water and eating good it would just go away.. dosent look like its going away just getting bigger and now i think there is a new lil small spot foaming on its fin, heres a new pic. the one you see on the side is on the tip of the fin.
