Personally I would take the pyramid out and add more wood and quartz. The pyramid looks out of place to me and detracts from the natural beauty of the fish.
Also you should check if things are safe before you put them in the tank......
It is your tank and you should do what you like with it. Those fish are stunning under the normal light. I think they lose some of their beauty when the different colored lights are on them.
I think it’s more preference. I like the look in the bright light, makes your amazing fish look so much better. I like the quartz too. Some prefer natural, some like off the wall different. In the end, what really matters, is if you like it.
