Ghost Shrimp Enrichment: Sold as Feeders, Kept as Pets

Ghost Shrimp Enrichment: Sold as Feeders, Kept as Pets

Most animals on this site arrive from a breeder. These arrive from a bulk feeder tank, and that shapes everything about how to keep them. For everything else about them, see our complete Ghost Shrimp care guide.

What the Research Actually Says

Nothing on the species, partly because "ghost shrimp" is not one species. The relevant evidence is the decapod sentience review, covered in full in our Cherry Shrimp enrichment guide.

Birch and colleagues applied an eight criterion framework to over 300 scientific publications and concluded decapod crustaceans are probably sentient. The UK then extended animal welfare law to cover them, shrimp included.

The report is careful about where the evidence is thinner, and the practical implication for an animal sold by the dozen as live food is straightforward enough: it is worth keeping properly.

Recovery First

The item that matters most and the one no care sheet lists. Newly bought ghost shrimp are often already stressed, underfed and damaged.

Acclimate slowly, by drip if you can, since sudden parameter changes finish off animals that are already marginal. Then give them a quiet, stable, planted tank and low expectations for the first fortnight. Losses in that window are common and are usually not something you did.

A 10 gallon tank is a reasonable home for a group and gives enough water volume to stay stable. Our tank setup guide covers cycling, which needs to be finished before they arrive rather than after.

Grazing Surface and Cover

The standard shrimp requirement. Dense live planting, moss, wood and leaf litter give both biofilm to graze and somewhere to hide.

The cover half is worth extra attention here, because a group arriving from a crowded feeder tank benefits from being able to get out of sight while it settles. A bare tank leaves nowhere to recover in.

Stable Water, No Copper

Copper is lethal and turns up in fish medications, some plant fertilisers and some tap water. Check everything.

Otherwise stability beats precision. Small regular changes, no sudden swings, and a cycled tank before the shrimp go in. Our health issues guide covers what a declining shrimp looks like, which is subtle until it is not.

A Safe Filter

A sponge filter is the sensible choice. It cannot draw a shrimp in, and its surface grows the biofilm they graze on, so it does two jobs at once.

Any other filter needs its intake guarded.

Moulting

Freshly moulted shrimp are soft and vulnerable and want cover until the shell hardens. Leave discarded shells in the tank, since the shrimp eat them and recover the minerals.

Failed moults usually trace back to unstable mineral content, so a steady general hardness matters more than any single number. Our moulting guide covers the process.

Watch the Big Ones

Some species sold under this name are opportunistically predatory and will take fry, very small fish, or a tankmate that is already weak. Larger individuals are the ones to watch.

This is not a reason to avoid them, and it is a reason not to put them in a tank with newly hatched fish and assume everyone is a herbivore.

Feeding

Once the tank is mature, biofilm and detritus supply a good deal of it. Supplement lightly with sinking food and blanched vegetables, and remove what is not taken.

Do not overfeed a small tank. Our feeding guide covers amounts.

Priority Order

1. A cycled, stable, planted tank waiting before they arrive
2. Slow acclimation, and low expectations for two weeks
3. Dense cover and grazing surface
4. Stable water, and nothing containing copper
5. A sponge filter or guarded intake
6. Old shells left in for the minerals
7. Light supplementary feeding

What Not to Do

Do not add them to an uncycled tank, which is how a cheap animal becomes a dead one. Do not acclimate quickly. Do not add copper in any form. Do not run an unguarded filter intake. Do not keep them with newly hatched fry and assume they are harmless. Do not remove discarded shells. And see our handling guide before netting them, since these animals have usually had enough rough handling before they reach you.
