When I had ghost shrimp, the first one died in about a month and a half (because the tank was cycling and I didn't know about it back then)....but I had ghost shrimp live for over a year and a half.
I then moved on to cherries and I loved them as well..
I now own amano shrimp andi love them as well! They are hilarious!
All shrimp molt throughout their lives
Made2party, some bettas just don't go with shrimp...some bettas just see shrimp as snacks instead of tank mates :-/ don't let this one experience steer you away from shrimp forever! They are great little additions to any tank! And mine are so friendly! The minute I stick my hand in the tank they are all over it! (except they steal my cories' food pellets >:( ...as soon as the pellets drop into the tank one shrimp at a time will steal them one by one and go hoard them...
