Sick Bettas, Already Lost One

[Snowdrifta421]

Something has recently infected 4 of my bettas, and I've lost one allready. At first I thought it was ich, but it has not been responding to such treatment, and it now looks like something different. They are larger than ich parasites, and instead of covering the whole body like ich will, there are just few on each fish, maybe two or three and they are on the head, under the scales, kinda look like white breadcrumbs allmost, and one fish is VERY pale, I'm going to see if I can get my camera to work so that I can post a pic of it, any suggestions would be MUCH appreciated.

Thanks

How big are the spots, do they have a circling of red on the outside, ir a red spot in the centre.

Just won't to check as i don't really know what you mean, but do they look like a clump of berries or a cauliflower.
