One of my shrimp has this, but doesn't seem to be currently berried. I never knowingly had a berried shrimp. Does this just mean it was berried at some point without me noticing?
Good chances, But they will also display this when becoming adults and molting rate will slow down. mommy shrimp will molt before releasing pheromones and a new berried shrimp will look freshly molted. But at this moment the eggs are super small and it can be missed easily.
It's very hard to size the baby survival rate in a community tank, most of the time you never see them until they feel confident enough to start swimming in the open. In a species tank they can start swimming around at 1.5 mm in a community they can stay hidden a long time up to 90+ days, If the adults are also hiding because of the other fish in the tanks it could be even longer.
I've never really understood how to specifically feed the shrimp in my community tank. They don't explore the tank very quickly, so the fish always find it first. (They scavenge enough to eat, but don't usually come around AT feeding time)
In a community tank, just overfeeding a little your fish will leave enough for a good bunch of adult to make a living.
The babies are a slightly different story. In the first 15-20 days they rely on biofilm and fresh algae, after that they go for the baby food.
It's not easy to find the hiding spot of the babies, once they start getting out in the open you can guess where they come from... Once established they always seems to get out and hang around the same place. When too much tiny babies are coming out in the open, it shows that they have trouble finding biofilm and dose their resting area with Bacter AE and baby food to help.
So... you can target feed this area with soaked finely crushed fish food with a pipette or a coral feeder. While your other fish are busy feeding on their side.
Shrimps will find the smallest pieces with no problems and at this size it might not interest the rest of your fish that much, leaving more for them.
