I know some people don't feed their coral or did it rarely. And then some people think I'm insane cause I feed at least every other day. I target feed very carefully, as not to cause unneccesary waste. I was told by my LFS that blastomussa wellsi doesn't need to be fed much at all and grows slowly...well mine likes eating a lot, lol. Here's a before and after (on right) shot of my blasto after 2 months in my tank. It has 3 new baby polyps distinctly formed around the parent head, with a fourth on the way.
