Welcome, I see you have good Taste in Corals, if you had any choice, but chose those 3.
The First Photo I actually like better, since a close up of LPS and LPS are my most favourite of all Corals.
Fairly easy to keep. Grow pretty quick if things are right.
They glow beautifully in blue light and they flow with gentle currents, and so much variety.
They are forgiving, if you are not rough and tear, cut them.
You can move them around, and when they split, multiply, you can prune and play with your setup like a garden.
I hope they do well, and so do other corals you get in the future.
