few is not few in the hobbyist sense, it means more that I have a few dozen berried, and I don't want to get rid of all of them
That means there are young, subadults, and other adults there but I am doing restrictred sales so as to not deplete the entire breeding colony. It can be iffy to reimport shrimp and have them come in well, so a majority of what I sell is home bred. If I sold ALL that I got, it would be a constant supply of unconditioned shrimp. I prefer to keep a good brood stock, bring in new (in a separate tank) and then mix them when they are conditioned.
