As for feeding it may be a little tricky at first, because a lot of times when LPS go without direct feeding they tend not to put out any feeders. What I would do is get some frozen mysis and use a knife to shave it into small pieces and dissolve them in some tank water. Then get one of thoe dissposable pipets, a lot of fish stores carry these or at least I've seen them in mine and should only be a few cents...if not an eye dropper will do the same thing. Turn the pumps in the tank off, and place a few small pieces of the mysis directly onto the heads and see if you get a feeding response. Just to warn you though, they many not react the first couple of times, or they may even over inflate trying to get it off of them. I had an open brain that I stopped feeding for about a year, and when it started to decline it took me a couple weeks of trying this every couple days before it finally started to feed again...but now looks great.. Hope that helps and let me know if you have any more ?'s.
