I'm with Zags on that one . . .from the sounds of it, doesn't sound anything at all like Ich, but I have the luxury of a high quality LFS with an in-house Vet that specializes in marine animals (great guy from India . . . always complains that my tank water is "beddy beddy hard" pH-8.2). A QT is definately in order for those guys you have there. Love my loach though . . . heard him make his "click" noise for the first time tonight.
Pictures would be fine, I did the video just for fun . . . however, should you decide to go that way, I created the video with Windows Movie Maker (everyone has it, most people just don't know it. It comes standard with Windows.) When it asks for compression, I put in that I want a 320x240 at a bitrate of about 360 Kbps. I used a Divx codec, but I don't remember which one. It brought it down quite a bit from its original size of 41MB to just over 10MB.
The original video was shot with a Kodak Easy Share Z760 Digicam.
