Live food for freshwater shrimp

Shrimp are grazers and scavengers first — but watch a cherry shrimp colony hit a sprinkling of microworms and you will see the other half of their nature: they are opportunistic protein hunters that pick worms off one by one. Used as a supplement rather than a staple, live food is a breeding-condition tool for neocaridina and Caridina alike.

The feeding plan

Stage	Feed this	Why it works
Protein supplement, 1–2× a week	Microworms, small sprinkling	Colonies — especially berried females and recovering shrimplets — use the protein; females saddle and berry more consistently on a supplemented diet
Shrimp-only tanks	A few live daphnia (moina)	Shrimp pick off dead and tired daphnia and hunt weak ones; in a fish-free shrimp tank a small daphnia presence is both food and clean-up entertainment
Shrimplets	Microworm traces + biofilm	New shrimplets graze biofilm first; microworm fallout on the substrate gives the bolder ones an early protein start
Before a breeding push	Microworms 2–3× a week for two weeks	The conditioning effect is visible in saddled females within a fortnight in most neocaridina colonies

Practical tips

Feed tiny amounts on the substrate or a feeding dish — shrimp find food by walking into it, and a small pile in one spot is found by the whole colony.
Live supplements never replace the base diet: biofilm, leaf litter and a quality shrimp staple remain the foundation.
In fish tanks, shrimp get the fallout — feed the fish their daphnia and let the shrimp scavenge; everyone eats.

Watch out: Overfeeding protein fouls shrimp water faster than it feeds shrimp, and shrimp are the first casualties of their own ammonia. Feed what is gone within a couple of hours — with microworms, less is genuinely more.

Common questions

Do cherry shrimp eat live food?

Yes — microworms are picked off individually and eagerly, and daphnia is scavenged (and occasionally hunted) in shrimp-only tanks. Think supplement, not staple: once or twice a week in small amounts.

Will daphnia harm my shrimp tank?

No — daphnia (moina) is harmless to shrimp and shrimplets. In a shrimp-only tank a few may persist and filter-feed alongside the colony; anything that dies becomes shrimp food.
