Filtration
Sponge filters are particularly useful in shrimp tanks because they provide gentle flow and cannot easily suck up tiny shrimplets.
Shrimp care
Neocaridina Care Guide
Neocaridina shrimp are often described as easy to keep, and they can be — once the aquarium is mature and stable. Most problems come from sudden changes, poor acclimation, unstable water or trying to correct parameters too aggressively.
The basics
Stability matters more than chasing perfect numbers.
Neocaridina can live in a reasonably wide range of water conditions, but they do poorly when those conditions swing suddenly. A stable aquarium that is slightly outside an “ideal” number is often safer than constantly adjusting pH, GH or KH.
Temperature
20–26°C
pH
About 6.5–7.8
Ammonia
0 ppm
Nitrite
0 ppm
Nitrate
Keep low
Do not obsess over one number.
GH, KH, pH and temperature all matter, but shrimp care is about
the whole environment. Consistency, clean water and a mature tank
usually matter more than forcing the aquarium towards a specific
value every week.
Aquarium setup
Give them surfaces to graze on.
Shrimp spend much of the day picking at surfaces rather than swimming in open water. A planted tank with wood, rocks, mosses and leaf litter gives biofilm somewhere to develop and gives shrimplets places to hide.
Plants & moss
Mosses, fine-leaved plants and floating roots create shelter and collect biofilm. Java Moss is especially useful in breeding tanks.
Hardscape
Driftwood and porous rock increase grazing area and give the aquarium more structure without needing to fill every centimetre with plants.
A mature tank
A newly cycled aquarium may technically process ammonia but still have very little established biofilm. Shrimp generally settle better into a tank that has had time to mature.
Feeding
Most shrimp tanks are overfed, not underfed.
Neocaridina constantly graze on algae, biofilm and tiny organic material in the aquarium. Prepared shrimp food should supplement that natural grazing rather than replace it.
- Feed small portions that the colony can finish without food sitting in the tank for hours.
- Use a varied diet rather than relying on one food every day.
- Blanched vegetables can be offered occasionally.
- Protein-rich foods can be useful in moderation, especially for breeding colonies.
- Remove uneaten food if it begins to break down.
More food does not mean faster breeding.
Overfeeding can raise waste levels, encourage pests and damage
water quality. A healthy mature tank already contains a surprising
amount of food for shrimp.
Moulting
A shed shell is usually a good sign.
Shrimp must moult as they grow. The empty exoskeleton can look alarmingly like a dead shrimp at first glance, but it is often transparent and split along the back.
Leave normal moults in the aquarium. Shrimp often eat them and reclaim some of the minerals.
Repeated failed moults can point to stress, unsuitable mineral balance, sudden parameter changes or poor overall condition. Avoid trying to fix a suspected mineral issue by making large, sudden changes.
Water changes
Keep them regular and sensible.
Neocaridina do not require dirty water, and “shrimp hate water changes” is a poor rule to follow. What they dislike is a sudden change in temperature or chemistry.
Regular partial water changes are useful for controlling nitrate and dissolved waste. Try to keep replacement water reasonably close to the tank in temperature and general chemistry.
Acclimation
Transport water and tank water can be very different.
New shrimp may arrive in water with a different temperature, hardness or pH. Sudden transfer can stress them badly even when both sets of numbers look acceptable on their own.
Gradual acclimation gives the shrimp time to adjust. Drip acclimation is commonly used for this reason, particularly when there is a noticeable difference between transport water and the aquarium.
Once acclimated, avoid adding the transport water to the aquarium if you do not need to.
Tank mates
“Peaceful fish” can still eat baby shrimp.
Adult Neocaridina can coexist with some small peaceful fish, but almost any fish capable of fitting a shrimplet into its mouth may eat one. If your goal is to grow a large breeding colony, a shrimp-only aquarium is the safest option.
Snails are generally easier companions because they do not hunt shrimp and often occupy a similar cleanup role.
Breeding
Healthy colonies usually do most of the work themselves.
Mature females carry fertilised eggs beneath the abdomen. These “berried” females fan and clean the eggs until they hatch. Neocaridina do not have a free-swimming larval stage — the young emerge as tiny versions of the adults.
Dense moss, mature biofilm, gentle filtration and a lack of predators give shrimplets the best chance of surviving.
Colour lines
Mixing colours changes what you get later.
Bloody Mary, Blue Dream, Yellow Goldenback and other Neocaridina colours are selectively bred lines of the same species. They can interbreed.
If maintaining a predictable colour line matters, keep different colour varieties in separate aquariums. Mixed colonies can produce offspring with increasingly variable or wild-type coloration over generations.
Common mistakes
What causes trouble most often.
- Adding shrimp to a newly established aquarium with little biofilm.
- Making large pH, GH or KH corrections in one go.
- Overfeeding because shrimp appear to be constantly looking for food.
- Using medication or aquarium products without checking whether they are safe for invertebrates.
- Keeping shrimp with fish and expecting every shrimplet to survive.
- Assuming every clear shell in the tank is a dead shrimp rather than checking whether it is simply a moult.
