Pregnant coral banded shrimp

Anyone have any info on pregnant coral banded shrimp? I've surfed the internet and cannot find anything on it. I've got a pair of cbs and the female for weeks now has a pouch of eggs underneath her. It used to be little and greenish in color. Now the pouch is huge and clear and clearly visible to the eggs. Yesterday I saw that pouch detach from her (except one side is still attached) and she like cleans it and puts it back. I'm not looking to do anything with these eggs, as I know it's impossible, I just thought it would be interesting to read what they are going through and how long their gestation period is. I cannot find a thing about it.
