How long do your Ghost Shrimp live in your tank?

[Octavarium]

I still have few that compete well with good stealing with the dojo,Kuhli, Orange mini CPO, and pygmy corys bottom crew. I think a good rule is to buy about 10 or so, and usually a few of the strong ones (odds are about 1 in 4 from pet store on average will be healthy enough to make long run if cared for peoperly by you) make it by few weeks, then you can rest easy for a while.

....on average since they come into my LFS more as "feeders" unfortunately, they are usually very unhealthy and in jam packed conditions. Soooo, if you ghosties live past the first 2-3 weeks (which is when the sick/weak ones usually die off) I find they usually live around a year from then on, maybe longer if you got them young.

This is also my experience. If you can get healthy ones, they often live quite a while - but the $0.40 feeder ones are usually pretty hard to keep alive. I bought more expensive tank raised ones on purpose because I wanted them to stay alive....and it worked.
