Help with my leather

[hawk82]

My leather coral used to be open looking and the arms all out and the polyps used to be out and it looked fuzzy. Now its kinda shrunk up and the arms are not as long and the polyps dont extent like they used to. What would cause this? Its been like this for about 6 months now. Ive include a pic of what it looked like before, and what it looks like today. Any help would be appreciated.

Used to look like this

now it looks like this

How are the lighting and flow? It gives the impression that its reaching towards the light. I also imagine there is no flow if its able to reach straight up like that.

I think maybe too much light.

have you tested parameters yet?

I think maybe too much light.

Ok now im getting somewhere. In the before pic i had my old led, a Razer first gen Maxspect r420r. Now ive got 2 Smatfam G3s, and I cant get any help with the % settings, but it is pretty low... 5% on whites, 40 on uv, and 60 on the blue. Should I try to lower it even more?

I dont know if its too much or not enough light, my parameters are in check nitrates around 5.
Tank is 40 breeder I have a Jebao sow 8 for flow, on else mode.

If you can, move to sandbed, leave for a couple days and move up another level and see if it opens....repeat till it finds a happy place.....IME, they really dont like too strong direct light....unlike yellow fiji's.....
and going from the picture, thats alot of light
