Larvatus Butterfly not eating

[hawk]

Were these fish sold to you as "Larvatus" or some other common name?. Hopefully it is a mis-identification. If they really are Larvatus, they are strict acro polyp feeders. I have only read of one person who kept these fish alive for more than a few months. He actually purchased browned out dying acros from a lfs. IIRCC, this guy lived in the UAE and had a huge, ultra sophisticated system. His Laravatus still eventually starved to death. Where did you purchase these fish? Good luck.
