Coral not opening???

[Corey523]

I bought 5 coral and it’s been 3 days and the only ones opening are the Kenya tree and mushroom. I have a hammer with 2 heads, a torch, and radioactive dragon zoas that have not opened yet. How long can it take for them to open?

Welcome to reef2reef !!!!
If you got them 2 days ago that’s normal but it comes down to the different lighting and water chemistry.

What's your water parameters?

What lights are you using?

Different corals require different light and flow intensity. I would experiment by moving them closer and further to light along with different areas of flow intensity.
