I got these from a friend and I have no idea what they are.

I also noticed green glass bubles in my tank as of recently. What are they and are they bad? Here is a pic:

What is this?

What is this?

I have tried to put these pics directly in the thread and cant figure it out

The first pic is some sort of LPS, I'm not sure what kind. The green glass bubbles are bubble algae, you'll want to pull them out without popping them. They're fairly invasive, and contain spores inside. The last pick is a trumpet coral I think.

First appears to be a Lobopylia or possibly a Symphylia valenciennessi.

Second is valonia sp? buble algae. It can be remove manually without too much concern about popping it. It needs to be quite mature to sporulate. It will only spread if there are excess nutrients but once established it can outcompete many things for available nutrients and sustain itself even in water low in nutrient.

Third,appears to be Caulastrea(trumpet or candy cane coral)
