[Dragon Hunter]

Has anyone ever used this product with their rays? I want to know if it is safe.

I use the black t-grade colorquartz with all my tanks and have never had a problem with it. Given, I haven't kept rays - just african cichlids and a huge fire eel. It's safe for fish, as long as you wash it well. To the touch it doesn't feel sharp enough to damage a ray's underbelly. I'm kicking around the idea of keeping/breeding motoros and I will most likely keep the colorquartz in (what to do with the frontosa colony is another issue).

i wouldn't chance it
it will probably iritate the rays belly over time
