Off the top of my head, The chili coral I believe is a non photo. So feeding will be required. The polyps, stand back and watch them spread. The fish, and the leather IDK.
A quick google on the betta says they are in need of a lot of care. I guess it is very tricky to get them to eat. It also stated they are tricky to get to eat froze or dead food. Black worms and Live food.Good Luck with him.
What I think................uhmmm. I think it all looks very nice, you lucky dog.
