I bleach my cleaning equipment after each use, but always use extra caution when rinsing them after they soak. Though it could have been I missed a spot of soap after washing my hands in between dealing with the tanks and my kids... Sorry to hear that you know the pain of such a loss, it sucks major donkey b*lls to have something like this happen :-( So far the fish that lived are still doing well, though my last eel (still haven't seen/found the missing one, going back to hunt again today) is very upset over the loss of his family. My husband and I are talking about getting some more baby eels to add to the tank, see if taking care of orphans will ease his pain (and have a secondary tank in case he gets mean with them of course... though I doubt I'll need it.). Thank God at least one lived, I'd have been truly distrought(sp?) if I had lost the whole line.
