Breeding and genetics
Track reproduction, care for young and select colour lines while accounting for ancestry and uncertainty.

Caring for a shrimp carrying eggs
Prefer to leave a berried female in her familiar, suitable aquarium. Eggs alone are no reason to catch her, raise the temperature or add more food. Continue maintenance and respond…

Breeding Taiwan Bee shrimp: track lineage and offspring
Taiwan Bee breeding combines water management with lineage management. Names such as King Kong, Panda and Blue Bolt describe trade forms, but do not predict fixed offspring proportions…

Breeding Sulawesi shrimp: start with the species, using Cardinal as an example
“Sulawesi shrimp” does not identify one species with one breeding recipe. Establish which animals you have first. For Cardinal, Caridina dennerli from Lake Matano, hobby keepers report…

Adding new stock to a shrimp breeding line
Add animals for a defined purpose, such as a documented cross or broader parental origin. Do not use “new blood” as an automatic cure for deaths or few juveniles. A new purchase does…

Breeding Neocaridina: from parent group to growing juveniles
Neocaridina davidi can complete development entirely in freshwater. Start with a suitable aquarium and a traceable parent group, then follow whether juveniles actually grow. One clutch…

Mixing Neocaridina colours: choose your breeding aim first
Different colour forms of Neocaridina davidi may belong to the same species. If they reproduce together, their commercial colour names cannot guarantee the offspring. A mixed display…

Neocaridina grades: what do Cherry, Sakura and Fire Red mean?
A Neocaridina grade usually describes a seller’s assessment of appearance, such as coverage and transparency. It is not a separate species or health certification. Ask which observable…

Identifying male and female dwarf shrimp
Adult female Neocaridina davidi are generally larger and fuller-bodied than males. Eggs carried underneath the abdomen clearly identify a female. Size, colour or active swimming alone…

Building and assessing a stable shrimp colour line
One striking shrimp does not establish a stable colour line. First describe the trait, keep parental groups traceable and assess the whole offspring group under comparable conditions.…

Shrimp inbreeding: a risk is not a diagnosis
Inbreeding concerns reproduction between relatives. It cannot be established merely from colour, body size or a smaller clutch. Relatedness may matter in a closed breeding group, but…

How large should a shrimp breeding starter group be?
No established minimum number works for every shrimp breeding project. Start with species, available space, known sexes and origin. Buying more animals may improve the chance of…

Keeping shrimp lines separate and their origins traceable
Separate tanks help only when transfers and labels also remain correct. Give each group a stable code and check it before moving an animal, plant or wet tool. Small shrimp can travel…

Shrimp breeding log: a practical record template
Give each group a stable code and record changes when they occur. Separate observation from explanation: “three juveniles seen” is an observation; “the others are starving” is an…

Shrimp genetics and colour: what can you really predict?
Seeing a colour is not the same as knowing its inheritance. The observable trait is the phenotype; genetic makeup is the genotype. A trade name such as Blue Dream does not…

Shrimp eggs disappear: hatched or lost?
Disappearing eggs may have hatched or been lost. First look for small juveniles on quiet surfaces and record what you actually saw: released eggs, an empty abdomen, or simply a female…

Selecting shrimp out: suitable housing and honest labels
A healthy shrimp outside your colour target still needs appropriate care. Selecting it out may mean removing it from the breeding group and providing suitable housing elsewhere. It is…

Breeding Crystal Red shrimp: follow water preparation and juveniles
Crystal Red breeding needs a repeatable water system and safe juvenile food access. Hobby husbandry often uses soft, low-KH systems. Active substrate and RO may be components, but…

Caridina grading: comparing Crystal Red and Taiwan Bee
There is no single grading scale for all Caridina. Crystal Red is often assessed by red-and-white pattern and coverage; Taiwan Bee also uses names for different pattern forms. Evaluate…

Setting up a shrimp breeding tank for adults and juveniles
A useful breeding tank lets animals live safely while you monitor food, growth and maintenance. Choose volume, floor space and filtration for the actual species and planned colony. No…

Helping baby shrimp grow: food access and safety
Growing freshwater dwarf shrimp need food, safe surfaces and suitable water at the same time. Adult survival alone does not establish that the tank supports juveniles. This check…

Breeding Amano shrimp: prepare the larval phase separately
Adult Amano shrimp, Caridina multidentata, are kept in freshwater. Their free-swimming larvae need separate saline-water rearing before juvenile shrimp return to freshwater. A female…
