Yes I think it would be just fine to use with them. I was using in all my sand sifter and shelldweller tanks without a problem as well as keeping Cory's on top of it and they never had a problem either. Even to the touch it doesnt feel any rougher than PFS or pretty much any other sand out there.
I seen it sold in 2 grit sizes, 20-40 and 60-80. The 20-40 is what your after, since the other is way too fine and I am sure it will end up compacting down way more then the 20-40. I have use it all of my tanks now, whether it is the only substrate or acting as a cap and cant really come up with a complaint yet. Just be sure to wash wash wash until no more junk is floating off the top and running pretty clear.
Hope this helps you!
