Do you have a lay box? I use a shoebox sized Sterilite container in my breeder tank with an inch of bed-a-beast. I keep it very moist during laying time and they will pile it all up on one side in a mound and lay in it. A couple years ago I used calci-sand and my feamles would dig a whole mess of it into the laybox and mix it with the bed_a-beast. I say as long as you get them quickly they will be ok the sand sticking too them never hurt mine any. Just keep an eye out to get them as soon as possible.
