Lime Yellow Amano Shrimp – Caridina multidentata "Yellow"
Lime Yellow Amano Shrimp are a selectively bred yellow color variety of the popular Amano Shrimp, Caridina multidentata.
They offer the same peaceful temperament and excellent algae-grazing behavior as standard Amano Shrimp while displaying a bright yellow to yellow-green coloration that stands out beautifully against dark substrate, green plants, driftwood, and rockwork.

Color & Appearance
Lime Yellow Amano Shrimp are known for their vibrant yellow coloration, which may range from lemon yellow to golden yellow or a slightly greenish lime-yellow tone depending on the individual shrimp, lighting, age, and environment.
Unlike standard Amano Shrimp, which typically have translucent gray coloration with rows of spots or dashes, selectively bred yellow Amanos have been developed to display significantly stronger yellow body pigmentation.
Individual coloration may vary naturally, and newly molted or stressed shrimp may temporarily appear lighter or more translucent.
Adult Size
Lime Yellow Amano Shrimp generally reach approximately 1.5–2 inches as adults.
Females are typically larger and more robust than males, making Amano Shrimp noticeably larger than many commonly kept Neocaridina shrimp.
Recommended Tank Size
A 5-gallon aquarium or larger can house a small group when water quality is stable, although larger aquariums provide more grazing area and greater water stability.
A mature planted aquarium is especially beneficial because it provides algae, biofilm, microorganisms, and other natural grazing surfaces.
Water Parameters
Lime Yellow Amano Shrimp are adaptable but should always be maintained in a fully cycled aquarium with stable water conditions.
- Temperature: Approximately 68–80°F
- pH: Approximately 6.5–8.0
- Hardness: Soft to moderately hard water
- Ammonia: 0 ppm
- Nitrite: 0 ppm
- Nitrate: Kept as low as practical
Like other freshwater shrimp, Amanos can be sensitive to sudden changes in temperature or water chemistry. Stable conditions are generally more important than targeting a single exact pH or hardness value.
Aquarium Setup
A suitable Lime Yellow Amano Shrimp aquarium should provide plenty of surfaces for grazing along with hiding areas for use during and after molting.
Recommended décor may include:
- Live aquatic plants
- Mosses
- Driftwood
- Cholla wood
- Rocks
- Leaf litter
- Shrimp caves and other hiding areas
A mature aquarium with established biofilm provides an excellent environment for Amano Shrimp.
Temperament
Lime Yellow Amano Shrimp are peaceful and spend much of their time actively grazing throughout the aquarium.
They do not normally harm healthy fish, other shrimp, snails, or live aquarium plants.
Amanos can be assertive around food and may carry larger pieces away from smaller shrimp, but this feeding behavior is not generally considered aggression.
Tank Mates
Lime Yellow Amano Shrimp can be kept with many peaceful freshwater community fish and invertebrates.
Potential tank mates include:
- Small Tetras
- Rasboras
- Small Danios
- Corydoras
- Otocinclus
- Peaceful Gouramis
- Neocaridina shrimp
- Other peaceful Caridina shrimp
- Freshwater snails
Avoid large or aggressive fish that may view shrimp as food. Nearly any fish capable of fitting a shrimp into its mouth may attempt to eat it.
Algae Control
Amano Shrimp are widely valued in planted aquariums for their strong algae-grazing behavior.
They may graze on:
- Soft green algae
- Some types of hair and thread algae
- Biofilm
- Decaying organic material
- Uneaten fish food
Even in aquariums with visible algae, supplemental feeding should still be provided to ensure a balanced diet.
Diet
Lime Yellow Amano Shrimp are omnivorous scavengers and grazers.
Suitable foods may include:
- Quality shrimp pellets
- Algae wafers
- Spirulina-based foods
- Biofilm-based shrimp foods
- Blanched vegetables
- Fish flakes or pellets that reach the bottom
- Other appropriate shrimp foods
Feed small amounts and avoid allowing excess food to accumulate and negatively affect water quality.
Molting
Like all shrimp, Lime Yellow Amanos periodically shed their exoskeleton as they grow.
After molting, the shrimp's new shell remains soft for a short period, and the shrimp may hide until the new exoskeleton hardens.
Shed exoskeletons can usually be left in the aquarium because shrimp often consume them to recover minerals.
Breeding
Lime Yellow Amano Shrimp have a more complex reproductive cycle than Neocaridina and many other commonly kept freshwater shrimp.
Adult females live and carry eggs in freshwater, but the newly hatched larvae require brackish to saline water during their early development.
Because of this larval requirement, Amano Shrimp generally will not establish a self-sustaining population in a standard freshwater aquarium.
Yellow Amano Genetics
Lime Yellow Amanos are a selectively bred color form of Caridina multidentata rather than a separate species.
Yellow Amano lines have been selectively developed for stronger yellow pigmentation while maintaining the general size, behavior, diet, and care requirements of standard Amano Shrimp.
Frequently Asked Questions
What species is the Lime Yellow Amano Shrimp?
It is a selectively bred yellow color form of Caridina multidentata.
How big do Lime Yellow Amano Shrimp get?
Adults generally reach approximately 1.5–2 inches, with females usually growing larger than males.
Are Lime Yellow Amanos good algae eaters?
Yes. They retain the excellent algae- and biofilm-grazing behavior associated with standard Amano Shrimp.
Are Lime Yellow Amano Shrimp peaceful?
Yes. They are peaceful freshwater shrimp suitable for many planted and community aquariums.
Can Lime Yellow Amanos live with Neocaridina shrimp?
Yes, provided the aquarium's water parameters are suitable for both types of shrimp.
Will Lime Yellow Amano Shrimp reproduce in freshwater?
Adult females can carry eggs in freshwater, but the larvae require brackish or saline water to complete development.
Are Lime Yellow Amanos the same as yellow Neocaridina?
No. Lime Yellow Amanos are Caridina multidentata and generally grow considerably larger than yellow Neocaridina shrimp.
Will every Lime Yellow Amano have exactly the same color?
No. Yellow intensity and shade may vary between individual shrimp.
