Cyanide Fish in Stores.......

I have recived fish before that I tested for cyanide with positive test results, the fish in question(small adult blueface,majestic angels) appeared healthy and vibrantly coloured, they ate eagerly a few hours after acclimation, after a couple weeks they started loosing colours and generally looking like crap, finns rotting, scales flaking off, very odd behaviour, death ensued shortly, upon inspection the meat of the fish was mushy and gellied, when touching various organs they would mush as though they were made of jelly,(the tissue was like jelly only minutes after death) tests confirmed cyanide and info on my find was passed on to a very major importer who quickly ceased dealings with the responsible collector... You cant visually diagnose cyanide poisining, so please dont make claims to have special powers in the future. All fish are worth thrying to save, dont give up, if you are desperate about a fish in poor health I can reccommend a good force feeding diet that has worked great for me, some on this list think of it as barbaric but if it saves your fish and no one is hurt, I dont see an issue....
