LPS that will adapt to just about any light. Yes they like to be target fed, and yes IMO they grow pretty quick, but you can't really tell at first. I bought one head, and 6 months later, I thought I still had one head, but then I noticed about 10 little baby heads being shaded by the one big one...
At about 9 months, all the little baby heads were visible.
I had mine in low flow, med/high light.
12 bucks a head is a pretty good price.
