A molt is part of growth
Shrimp leave their old exoskeleton as they grow. A normal-looking shell does not by itself show that the animal needs a new food or supplement.
Newly molted shrimp may rest or stay under cover. Avoid disturbing them or forcing them toward a feeding spot.
Keep the routine familiar
Offer the usual appropriate food in a modest portion when the colony is ready. Remove leftovers and observe the tank as you normally would.
Do not add calcium or change water hardness solely because a molt happened. GH, KH, diet, and water stability are separate pieces of the picture.
Investigate a repeated concern
If multiple shrimp struggle to molt or die, test the water and review any recent changes. A repeated pattern deserves attention beyond meal timing.
Seek informed advice with the tank history and readings if the issue continues. Avoid medication or additive guesses.
