First off, were did your Live Rock come from? Did you buy the rock from one of the tank break downs locally or from a LFS/online. This makes a difference when we try to age the system. I've had lots of people tell me the tank is only a couple weeks old when they bought some of Jim's rock for instance. This is actually a move and not a new set-up. New to them but not new in reality. If it was bought online or from the LFS you need to wait 6 months to 1 year before even trying these two corals. Goniopora is very difficult to keep and even the pro's are unsuccessful. I am going to try it one more time feeding with cyclopeeze to see if I can have one. I have 2 corals that are very simular to the goniopora that I have been feeding with cyclopeeze that have not died off at all and actually seem to be growing. as for the BTA they are one of the hardiest anemones and should recover if the parameters are all fine. They die very easily if you nitrates or phosphates in the tank though. I have had great luck with rufugiums and keeping these anemones. I have had well over 100 anemones pass through these tanks and a lot of them have been residents for extended periods of time. I currently have 5 that have been with me for over a year, splitting and happy.
