White Spots On Clown Loach

[sailorxo]

This white spot started two days ago, mostly on the back fin. It doesn't really look like Ick to me, it's just white dots. I am sorry for the quality of the photos, but my fish don't like to pose for cameras. I am worried and really want a second opinion to what is going on because I start treatment.
 
Thanks.

Anyone have any ideas ?

As you say, difficult to tell from the photo, but if you're sure that it's not Ich (Whitespot), then I'd say it's the beginnings of a fungal infection. 30% water changes for a week should clear it up, if I'm right.
 
I would also say 20% weekly change isn't quite enough - make sure you're on the high side of the 30% mark.
