Hi there, I have had my sw tank for 3 weeks now, added chemicals in so I could add fish within instantly (but I waited for a few days). I’m adding tomorrow a royal gramma, and maybe a cardinal, but I was wondering if it’s safe to put a goby in when I have a patch of cyano on the sand.

Also it is better to add livestock from least to most aggressive to a tank. Welcome to the hobby and enjoy.
