    0 Not allowed!
    hi i had 2 rcs die almost immediately after a 10% water change but before that they were flying round the tank eating bloodworm climbing (the usual) did my water change and bam on there back twitching

    i read somewhere they are sensitive to de-chlorinator ?

    any help would be appreciated

    More details required please:

    Are you in fact using Dechlor? [Never heard of dechlor sensitivity wrt RCS btw]
    Tank size? How long it has been cycled and H2O parameters?
    WC schedule?
    Other stock?
    Gas mileage isn't everything OIIIIIIIO
    Lack of planning on your part does not constitute an emergency on my part.
    Why pretend there are no stupid questions? Actually, There are many stupid questions: "Should I drink this bleach?" Is just one example.
    Having said that, Just because it's a stupid question doesn't mean that it shouldn't be asked. It's better to know.

    A warm beer is better than a cold beer. Because nothing is better than a cold beer, and a warm beer is better than nothing.

    Nitrite will kill. Deaths this instant would make me highly suspicious of the water you used.

    I have dozens and dozens of RCS. I probably kill 20 a week myself with changing out filter media and water changes. I move a plant and they fall out of it, jump around on the floor until I can catch them or jump down my sink.

    Never lost any due to dechlorinator but you will kill them if you don't use it.

    If your worried about dechlorinator there are shrimp specific ones you can buy. I lost 12 shrimp in the same way your describing so I know how you feel with this. Someone on here suggested there may be copper or other heavy metals somewhere in the tank or in the tap water when I had this problem. It might be worth testing for that in case your throwing lethal stuff in from the tap water.

    The quickness of death would fit with heavy metal poisoning. Typically you'd see them curl up, wither a bit and die within minutes.

    Sounded to me as the dechorinator is not working to remove chorine fast enough so I went into search mode and found this that may be interesting.

    What made me think of this is some junk Big Als sold, stating it removed chlorine and chlormaines, that was FALSELY STATED and it did not remove chloramines at all. Screwed up cycles in 4 fish tanks all at once.

    Never thought of that one, could well be it. Good call!
