My first coral was polyps that hitchhiked off of a fellow maast member when they sold me their live rock. My tank is now swarming with them

It's ok though... the dull polyps just make the colorful stuff stand out that much better!

I found that zoas were really easy to keep. Mushrooms are fun too, but for whatever reaons I have had a harder time with them... maybe too much lighting, or whatever, but they always loose color and then have to regain it over months.
