How long does it take a neocaridina shrimp to grow full size?

Hi,

The shrimp is 6mm or so, how much time would it take before you expect to see it full size?

I don't keep records/ measure but from memory it's about 4 months at most, depending on temperature and food. At 6mm it is already roughly 3-4 weeks.
