I'm starting to see nameless corals that look just as nice as many of the high end, big named corals. Granted, I know there are plenty that won't compare, but there are some out there. Some people are very proud of their corals and charge an arm and a leg for a frag, and colonies are untouchable. Then again you come across some colonies that are well priced and are great looking in their own right. I think it's 100% up to you. If you like it and it's something that would look good in your tank, screw it, buy it. I'm learning quickly that it's not all about names in this hobby, just like any other. The big guys will always be big, and there are people that will buy their stuff. Then again there are those that see beauty in each piece separately and don't worry about names.
I think you did a very good job picking up this coral. Congrats on bringing it back to life!
