I had 2 bamboo shrimps for over 6 months one die two days after a successful molt.
May be the stress killed him.
The second one is alive sits on java fern branches in front of the water exiting from the external filter and feeds himself.
I feed him n other tank inhabitants Tetra pro color crushed to powder, Mosura baby, Tetra min baby fish powder.
In addition other shrimps get Shirakura ebidama, Mosura Spinach and barley.
