if we are able to avoid the larva being eaten. That's 50% of the breeding problem solved. I like the opae ula related's idea of moving the berries shrimp to a separate tank. But I think you still need to get a vossen larva trap unless we are sure the mother shrimp doesn't eat her own young. If she lays them in the night, the larvae will "disappear" again if she does eat her young.
Yeah "if" they eat there young. This all sounds familiar, I think we discussed this in the past. In the natural setting, they are released in the lava tubes near the ocean and they have to find their way there to survive.
