Very cool Rob. Maybe the berried shrimp and larvae will encourage the others to reproduce. If you look with a hand lens 7x at the larvae you see their little legs are in constant motion. You have to ask where do they get their energy. You may consider reducing the volume of air bubbles to reduce currents. i really am not sure if the current is bad but where they are from there is no water movement/current. Not to jinx you but do not be concerned if a berried shrimp begins to drop her eggs over several days. I have had this happen for no reason i could discern. I have read that others have experienced this.
