Clownfish breeders use a small piece of slate to encourage clownfish to spawn on it. I have seen slate in cold water tanks with nps corals. I can only assume it is fish and invert safe.
Wow...I love the look of slate, I kept it in my freshwater tanks, and all this time I could have used it.
I did find this tidbit of information:
The best choices are lava rock, reef rock and live rock. Limestone, reef rock, live rock and tufa rock are all alkaline in nature and will help to buffer your pH and keep it at the higher level required for a marine tank. Lava rock, slate and petrified wood do not effect your pH, and some of the buffering capacity in your tank may be lost, so
you will have to keep a closer watch on your pH then you would using the others.
