If it can be used in aquatic turtle habitats I don't see a reason why you can't use it with fish, it's not chemically treated or anything, but I would let the aquarium sit for a while before putting fish in it to test for any effect the sand may have on pH. I'd put a sponge over your intake to help keep sand out.
