Come on brother, don't turn this into something it isn't. No one was being sarcastic. If I was I wouldn't have bothered with LOL. I told you your statement was silly because it was. Just because someone bought something at an LFS does NOT automatically guarantee it's "safe". That's the issue I took up with you, nothing more. The rest was my own experience. Why don't you post the chemicals these shrimp are treated with? I'll take it a step further and call the vendor listed on the bag come Monday and ask them myself what chemicals the shrimp are treated with before being shipped. Why would polyphosphates, that apparently can be be rinsed off as suggested by experts kill a fish? At the risk of "confusing" me further, could you explain what exactly lead you to the conclusion that chemicals on raw frozen shrimp purchased at a grocery store were the cause of your 3 fish deaths? Did the fish suddenly grasp their throats with their fins and begin choking motions? LOL. This is the first I have ever heard of anyone contributing a fish death to feeding raw shrimp. I think a poll would be a great idea. I'd like to see how many others have had the same experience. Like I said, I have fed without doubt more than a quarter ton of raw shrimp to thousands of fish over the years without causing the death of a single one. I feed raw chopped shrimp at every single feeding even to this day. I think you're stretching pretty far if you're going to insist that I haven't had a death yet simply because of luck. No one's luck can pull through those odds. Your own post said that most shrimp are probably safe! So when I say I never had any problems what in the world are you in a huff about? Maybe the shrimp did cause your fish deaths. Who knows? I couldn't care less because through my experiences it's definitely the exception and not the rule. Like I said before, my issue was with your statement that just because something was purchased from an LFS it guarantees it's safe. That's a very broad statement and absurd. There was no sarcasm then, there isn't now. I'd appreciate if you didn't try and spin things in a way they weren't intended.
