Red Rili Neocaridina Shrimp – Tank-Bred in Texas | Peaceful Algae & Biofilm Grazer, Juveniles/Subadults

Red Rili Neocaridina Shrimp are peaceful, active, and colorful freshwater shrimp known for their bright red markings and clear or translucent body sections. Their red-and-clear pattern, small size, and constant grazing behavior make them a great choice for planted tanks, nano aquariums, shrimp colonies, and peaceful community setups.

These shrimp are tank-bred in Texas, making them a stronger and better-acclimated option compared with many imported shrimp. They spend much of their day grazing on soft algae, biofilm, plant leaves, moss, driftwood, rocks, and aquarium surfaces. They are also excellent cleanup crew animals for lightly eating leftover food and natural growth in a mature aquarium.

The shrimp currently available are juveniles/subadults. Adult Red Rili Neocaridina Shrimp typically reach about 1 inches when fully grown.

Recommended Tank Setup

Red Rili Neocaridina Shrimp do best in a mature, fully cycled aquarium with stable water, live plants, moss, driftwood, leaf litter, and plenty of surfaces for biofilm growth. They are peaceful and can be kept in shrimp-only tanks or with small, calm community fish that will not harass or eat them.

Minimum Tank Size: 5 gallons recommended
Group Size: Best kept in groups of 10 or more
Temperature: 68–78°F
pH: 6.8–8.0
Substrate: Sand, planted tank substrate, or smooth gravel
Tankmates: Peaceful nano fish, small rasboras, endlers, guppies, corydoras, snails, and other peaceful shrimp-safe tankmates. Avoid 

Live plants, moss, floating plants, driftwood, and leaf litter are strongly recommended because they provide grazing surfaces, hiding places, and natural biofilm. Sponge filters or covered filter intakes are recommended to protect baby shrimp.

Tankmates to Avoid

Avoid keeping Red Rili Neocaridina Shrimp with aggressive, predatory, or fin-nipping fish. Many larger or more aggressive fish may chase, stress, injure, or eat adult shrimp and baby shrimp.

Tankmates to avoid include:

Betta fish with aggressive personalities
Cichlids
Angelfish
Goldfish
Large gouramis
Barbs
Large tetras
Puffers
Loaches
Arowanas
Oscars
Any fish large enough to fit shrimp in its mouth

Feeding

Red Rili Neocaridina Shrimp are excellent algae and biofilm grazers, but they should still be fed directly in clean aquariums. They enjoy a varied diet of:

Shrimp pellets, algae wafers, biofilm, blanched zucchini, spinach, nettle, green beans, Indian almond leaves, shrimp minerals, powdered baby shrimp food, Repashy, and occasional high-quality sinking foods.

They will graze on soft algae, biofilm, plant leaves, driftwood, glass, and leftover food, but they are not a replacement for regular feeding or tank maintenance. A balanced diet helps improve color, breeding, molting, and long-term colony health.

Important Notes

Red Rili Neocaridina Shrimp are hardy, but they still need stable water conditions. Avoid sudden changes in temperature, pH, or hardness. Copper-based medications can be harmful or deadly to shrimp, so always check treatments before use.

They may breed readily in stable aquariums with good food, hiding spaces, and shrimp-safe tankmates. Baby shrimp are very small, so dense plants, moss, and sponge filters help improve survival.

Live arrival guarantee. Please acclimate slowly and place them into a fully cycled aquarium.
