Neocaridina dwarf freshwater shrimp

The Neocaridina is one of two families of freshwater shrimp that have become quite popular in recent years in the aquarium hobby. You can find more information about some of the different types of neocaridina via the links listed below, but I will give some general information on this species on this page.

Typically they grow to around 1 inch. Some specimens may reach 1.5 inches. The females are typically larger than males.

Shrimp are born like miniature adults. They can be very tiny. Adult shrimp do not eat their fry, however other fish would as long as the shrimplets are small enough to fit into a mouth. The same can be said of older adult shrimp if kept with larger fish.

They can tolerate temperatures between 60 and 85 degrees Fahrenheit. Although, it is said that they can survive in cooler temperatures (I have read of some in Florida keeping them in ponds year round.) Their breeding slows under 70 degrees Fahrenheit and peaks between 72 and 78 degrees Fahrenheit.

They can be prolific breeders. All they need is a good clean water environment, male and female shrimp, plenty of food and you will see on average around 20-25 eggs per brood and it can take around a month for the brood to hatch. (Sometimes you may see more – I’ve seen some claim 25-50 eggs per brood.)

They can adapt to a fairly wide range of pH 6.5-8 although possibly even a greater range.

Females can usually be distinguished by either a “saddle” which are the eggs visible on the back in the shape of a saddle, or eggs on the swimmerettes. Or, by their size (larger than males), body shape can also be an indicator. Females have the shell coming down further as a “shield” around the swimmerettes at their rear quarter. Males tend to have more of a straight across (or concave) line on their back abdomen.

All of these shrimp prefer to have plants so they can climb (and take cover). They do molt as they grow and will take cover after they have molted. All of these species are native to south Asia (Taiwan in specific for many.) Colored varieties are not found in the wild, but have been bred for the aquarium hobby.
