I am on my second Foxface Rabbitfish from Absolutely Fish that was fine for about a month and a half and then went downhill overnight and died. I have 3 other fishy inhabitants that are perfectly fine that have been in the tank since it started. From what I have read after a few google searches it seems to me that the symptoms are consistent with cyanide poisoning. Does MAC certification really mean anything, I mean can the importer really have any idea regarding the methods under which their fish are caught?
