Question on Zoa and Acan

[Braveheart!]

One of my Zoa frags is shrinking and not opening (opens and closes). I thought the Par maybe was too high, so I placed it under a ledge, but it still isn’t doing well. Wonder what I should try and where to move it. (FYI - I’m trying to get better as a reefer and willing to take a chance and move it to learn, but where it is isn’t working). The Acan looking like it is closing and on it’s last leg. I think it is getting the highest par of all my acan’s, but all the others are doing well. I have redsea led90’s at 45% blue. My guess is my par is around 150. Any input would be great. Thanks

It may not be a light issue. What are your tank parameters?
Zoas are pretty tough and can survive just about anything. Any chance they are getting direct flow, or something touching them? Lots of possibilities here. How new is the tank?

The tank is 10 months old and everything else is doing fine. The Acan could be a flow issue
