Nice! I've been getting berried females almost constantly and it's exciting! Always check your filters; even with prefilters, sponges and double-nets over the intakes, I check my filters carefully monthly (HOB and canister) and I always find at least 5 shrimplets of varying sizes. Some of them are SMALL, almost hardly visible, so get an extra bucket and check small portions of water at a time with a flashlight. Also check buckets when you do water changes to make sure you haven't sucked up any shrimplets (I use an automatic water changer from the faucet but I'm paranoid about sucking up anything so I siphon water out with buckets then refill from the faucet).
Give the shrimplets places to hide (moss, dense plants etc) so they don't become food for other fish (if you have other fish in with them ).
