Ghost shrimp eat a mixed diet: surface growth, small organic particles and suitable prepared aquarium food. Feed them directly when necessary rather than assuming fish leftovers will supply everything. The useful question is whether your shrimp can find and consume enough food without leftovers spoiling the water.
What to offer
Use a complete sinking shrimp food or a suitably sized bottom-feeder food as the main supplement to natural grazing. Break large portions into several small pieces so one shrimp cannot carry away the entire meal. Rotate occasional additions rather than replacing the main diet with one vegetable or frozen food.
- Prepared food: small shrimp pellets, softened wafer fragments or flakes that reach the shrimp.
- Occasional animal food: a small portion of suitable thawed aquarium food, offered where shrimp can reach it.
- Vegetable supplement: a small, clean piece of blanched zucchini or another appropriate plain vegetable. Remove what is not eaten.
- Natural grazing: established biofilm and soft surface growth on plants, wood and other aquarium surfaces.
The supplier Ghost Shrimp Co. describes small supplemental meals alongside natural grazing. This does not mean every tank supplies the same amount of food. A newly arranged display with clean surfaces differs from a mature planted aquarium.
How much and how often?
Begin with a very small portion and watch the group feed. In a mature aquarium, a small supplemental meal every other day is a reasonable starting trial; adjust it to actual consumption and available grazing. A heavily stocked shrimp-only aquarium may require more frequent feeding than a lightly stocked community with accessible leftovers.
Check the feeding spot afterward. If food remains, remove it and reduce the next portion. If fish take everything before the shrimp arrive, feed a second sheltered location or offer food after the fish settle. Do not increase the entire tank’s ration just to get a few crumbs to the bottom.
A shallow feeding dish makes leftovers easier to see and remove. Record portions briefly if several people feed the tank. Food left by one person can otherwise lead another to add a second meal.
Do ghost shrimp clean algae and waste?
They graze some algae and organic surface material, but they are not a treatment for every algae problem. A field study of eastern grass shrimp and periphyton found complex effects involving consumption and nutrient recycling. Eating material does not remove all its nutrients from the aquarium.
Continue normal aquarium maintenance. Remove dead fish and snails promptly instead of leaving them for shrimp to dismantle. Address excessive light, accumulated food and other causes of algae growth; do not starve shrimp to make them graze harder. Amano shrimp are another grazer option, but they also need appropriate care and supplemental food.
Predation and young shrimp
“Ghost shrimp” can refer to different animals, and scavenging does not establish that a shrimp never takes live prey. Avoid guaranteeing the safety of fish fry, tiny snails or newly molted shrimp, especially in mixed shipments with uncertain identification. A shrimp feeding on a dead animal also does not prove it killed that animal.
Newly hatched larvae need a different assessment from adults picking pellets off the substrate. See ghost shrimp larval rearing for a separate nursery approach. For water, filtration and identification, use the main ghost shrimp care guide.
