Has anybody used either of these in a tropheus or tanganyikan tank?

I'd never heard of either so i googled them both a d they look sweet mate...no reason at all why they wouldn't work in a troph scape...i like the black stone better personally

I'm using Seiryu Stone in my tank right now (you can see photos in my signature). Still waiting for green algae to grow on them though.
