Adam, Here is a coral I got as a small frag for free from a buddy and after about 3 years I took it out this past weekend to cut it back to a smaller colony because it had reached the surface and was growing sideways! Here is a picture of it sitting on a 5 gallon bucket and there was also a starry night colony next to it the same size that I had to also cut back as well as other, but those were the 2 largest!
