Breeding ghost shrimp starts with identification. The eastern grass shrimp, Palaemon paludosus (often listed as Palaemonetes paludosus), can reproduce in freshwater. Other animals sold as ghost or glass shrimp may have different larval requirements. Do not add salt simply because a transparent shrimp is carrying eggs.
Eggs are the beginning, not a successful colony
A berried female carries eggs beneath her abdomen on the swimmerets. After hatching, eastern grass shrimp pass through larval stages before becoming bottom-crawling juveniles. This differs from cherry shrimp, which release miniature shrimp.
Egg development and the duration of larval stages depend on temperature and species. Avoid predicting a hatch from a fixed calendar or assuming egg loss always means successful hatching. Check for larvae and later for growing juveniles.
For an example of that distinction, miniBIOTA’s firsthand observations documented ghost shrimp larvae but could not confirm that they survived to the juvenile stage. A berried female or a few visible larvae alone does not prove that the setup supports a lasting colony.
Prepare a nursery before moving a female
Set up a small, fully cycled nursery with water matched to the adult aquarium. A 5–10-gallon tank is a practical project size, with gentle aeration, a mature fine sponge filter and sheltered surfaces. Keep fish out and protect every intake. More volume helps maintenance, but it does not supply food automatically.
Transfer a berried female gently in a submerged container when a move is necessary. Avoid repeated netting and chasing. After hatching is confirmed, return her to the adult tank without carrying larvae along. Separating adults reduces one potential source of losses and makes the nursery easier to observe.
A bare area makes siphoning and inspection easier; some mature moss or other suitable cover provides surfaces for settled young. Avoid dismantling the nursery or stripping all its established growth during the attempt.
Feeding and daily checks
Plan food for the identified species and developmental stage before hatching. A pellet on the bottom is not a complete strategy for larvae suspended in the water. Cultured microscopic foods can be useful nursery resources, but neither a generic green-water bottle nor spirulina powder guarantees that larvae receive suitable nutrition.
Offer very small amounts, observe whether food is being captured, and monitor the nursery for accumulation. Once juveniles settle and begin grazing, introduce finely divided appropriate shrimp food. Do not pour in large powder doses to compensate for not seeing the larvae eat.
Check temperature, aeration, ammonia and nitrite; the latter two should remain undetectable. Remove debris with thin tubing into a light-colored container and inspect the removed water before disposal. Replace water gently with matched, conditioned water. Filterless tanks require their own established management and should not be treated as automatically safe because larvae are small.
When to return young to the main tank
Wait until juveniles are visibly crawling, feeding and growing, then assess the hazards in the destination tank. Age alone is not a safe transfer rule. Fish, strong intakes and adults of uncertain identification can still threaten young shrimp.
If larvae disappear, review species identification, feeding, intake protection, water quality and possible predation separately. Do not assume every failed attempt requires salt or higher temperature. Amano shrimp have a different larval rearing problem; their saline-water method is not a universal ghost shrimp recipe.
Keep notes on hatch dates, observed stages and surviving juveniles. Use the adult care guide and feeding guide for maintaining the parent group between attempts.
