Here's what you have to do.
Water change. Run carbon.
That's all you can do. Those are ricordia floridas, and are very hardy. There must have been something in your water or a quick parameter change to bring on this problem. Stop the 2 part for now until you can get your water into balance.
I would do a series of water changes quick.
