What's This White Stuff?

It almost looks like sand but I assume it isnt cause youd know that. I do know that the ray in the back left looked FUBAR and curling real bad!

Have no idea... I fed them last night, all ate fine.. Woke up this morning, all look like that, and yes two females were "curl up" already. The one in the picture is still alive, but I gotta go to work, and couldn't do anything yet, besides removed the two "curly" ones Told you bro, I'm the HAMMER... BTW, my tank is bare bottom, and I did my weekly water change last Saturday night
