Dead Fishes!

[DazedNCoNfUsEd]

Hey guys. Well right now I'm in the middle of the desert in Iraq doing a little deployment for a few months. Well I left my tanks for the wife to take of, and apparently last night she did a water change but forgot to put the dechlorinator in before adding the new water (bad wifey). Now she said 5 of my tiger barbs have died, but everyone else looks okay.

My question is about the good bacteria. It was about a 20-25% water change apparently, do you think that's enough to kill off the bacteria? I told her to feed them once a day every other day for a couple of weeks, just as a precaution. Is that good advice?

Also I wrote an email detailing every step involved in a water change for her to use as a reference from now on.

sounds a bit quick for the fish to die you`d expect a day or two, even fish being used for cycleing live longer than that

There is doubt into if decholrinater is actually needed (I learnt this from andywg) so he would be able to tell you about it in more detail. From what i understand if the tank is fully cycled tap water should be fine.
