What does a brain coral need to thrive? Good calcium/alk
levels, proper salinity, temp, pH levels. Adequate lighting (VHO
), and moderate water flow (not too much - it will tear its flesh). A nice supplemental feeding of a small chunk of raw seafood weekly or so - yes, they have tentacles.
Marine Snow, IMO
, is worthless - and there is an analysis published on the 'net somewhere (I can dig it up if you'd like it) - proving that is 99% water.
What methods are you using to maintain calcium & alkalinity - & do you have decent test kits to monitor these levels? As BBReef said, this applies to all corals, not just Brain corals.
Not sure if you are referring to the Open or Closed brain coral, but here is a good article on the Open Brains:
>>Open-Brain, Rose Coral, Family Trachyphylliidae<<
And one on the "Closed" brain (first of three parts): >>Brain, Meat, Pineapple Corals, Family Mussidae, Pt. 1<<
