Over the past few weeks my clam has slowly been bleaching. The original spot was very very small but now covers two ruffles of the mantle. Also the parts that are bleached are pulled in. After reading a bunch there was only one article that seemed to have an answer, the cause being an infection, but didn't go into depth about it, stating that there was nothing that can be done. I've looked everywhere for how to fix this and there doesn't seem to be any method out there. Has anyone ever encountered this and stopped the progression of the bleaching? I read a forum post where it has been stopped before but didn't say how it was stopped.
The first signs were five weeks ago. The photo is what it is now and what it looked like at the beginning. I did a fresh water dip for 25 minutes and the clam re-opened 15 minutes after placing her back in the tank. The dip was four days ago from the picture, so the pulled in mantle isn't changing. The clam still fully opens and reacts to change in light. The clam has been in the tank for a year and a half, and is roughly 5-6 inches.
