Congratulations! You don't know the names?
A few hints for the future....The first thing to do is always study up and find out what your coral likes, also (you did nothing wrong, don't worry) I wouldn't glue the coral to a rock until I was sure it was happy in that spot.
You will find that some corals will do well while others just die. Some corals like lots of light and some not so much, same thing with water flow. The green is a frog spawn and the other is clover...LOL..I think.
This book was very helpful for me when I was keeping corals...
