I am new and think that it might be White spot as the growth is white around the edges. Look like its getting bigger by the hour. No other fish in the tank have nayhting like it on them yet.
What do I do?? I do have a small tank that I could perhaps set up, I have salt, white spot cure, tonic that all came with my tank.
I would take a picture but its too fast and just keep getting a blurr!!
