Black fluorite and black sand in general (like tahitian moon) is a very sharp, jagged sand. I would not recommend it with bottom dwellers with very soft skin, like an ACF.

Do not wager it would pass through their digestive tract if swallowed very well either, you'll want a smoother sand.

I also wanted black sand for my tanks but after doing a lot of research (and wasting money) I came to realize that black sand is sharp silica sand (glass) or coal slag (black diamond).
