def not the invert,
keep that coral in shaded and low flow areaa and feeeeeed it, and itll come back.
they are really hardy corals,,
i sold some corals to a guy on ebay once, who told me when hurricane katrina hit his area, and his tank basiclly crashed,(not literally) his acans and other lps were the only survivors.
ok that was random, just saying, im sure your coral will come back
