I've had my tank at work for about 2 years now and it's doing well. No babies yet, but shrimp seem content. However, my snails keep dying and I don't know why.
I've had 4 snails in there so far (not at the same time; when one dies, I bring another one over from my tanks at home). They seem to be ok for a few months, then I notice there will be a bout a 2-week period where they seem to move slowly (even by snail standards) and I think they are already dead because they are just staying in the same place for hours or days. Then they unexpectedly move again. But then a few days or a week later they'll just be dead. It's the same pattern every time. Last time, I brought 2 snails and they have now died about a month apart. Any ideas what could be causing this?
I wonder if some kind of contaminant is in that water, given that you are keeping snails alive just fine in your home tank. I'd mix a triple batch of new water, sieve out the shrimp and put them aside, dump the tank water, rinse the tank and everything from the tank in new water, then fill it with new water, restore the shrimp, let things settle down for a couple weeks, and try again to put a snail in there.
If you get everything from Mustafa -- shrimp, snails, chaeto -- you can minimize the risks of introducing unwanted organisms or chemicals.
