nothing to worry about, if anything sand is softer.
do you dry your hands with a towel? or sandpaper?
fish aren't any different. they won't sift through
any surface that could injure them, such as lava rock.
Onyx Sand, like Fluorite is not coated, which does
not make it more abrasive to fish, simply dustier.
