They are amazing! Some have quite a sting though...even to a fish! Since we got off topic from coral I might as well mention that starfish are my all time favorites! I've got 3 Fromia indicas ATM...one has well outlived any expectations and i assure you the others are headed the same way! As far as corals go, I am a fan of SPS but can't say I like it more than LPS necessarily. I love Scolys and NPS more than any others probably!I had to think about that for a minute, I am aiming for a mixed reef but when I look at what's dominating my tank I gotta say Anemones.
I love anemones, got a bubble tip(actually 6), a few mini maxis, a rock flower, an adhesive and a tube anemone. They are such interesting animals.
