Shrimp-Safe Aquatic Plants & Care Guide

Creating a planted aquarium where shrimp can thrive requires careful selection of aquatic plants and attention to water quality. Shrimp, particularly popular species like cherry shrimp and Amano shrimp, are sensitive to chemicals and copper, making plant choice and maintenance practices crucial. This article provides a comprehensive guide to building a shrimp-safe planted tank.

Why Plant Choice Matters for Shrimp

Shrimp are far more sensitive to water quality parameters and chemical contaminants than most fish. Many commercially available aquatic plants have been treated with pesticides or growth regulators that can be lethal to shrimp. Even trace amounts of copper, found in some fertilizers and medications, can kill shrimp within hours.

• Pesticide risk: Farm-raised plants may carry residual pesticides. Always quarantine new plants for at least 1-2 weeks before adding them to a shrimp tank
• Copper sensitivity: Shrimp are extremely sensitive to copper ions. Avoid any fertilizer or treatment containing copper
• Lead weights: Some bundled plants come with lead weights that can leach heavy metals. Always remove these before planting

Recommended Shrimp-Safe Plants

The following aquatic plants are known to be safe and beneficial in shrimp tanks:

• Java Moss (Taxiphyllum barbieri): The ultimate shrimp plant. Provides shelter for baby shrimp, grows biofilm for grazing, and requires no special care. Attach to driftwood or stone
• Java Fern (Microsorum pteropus): Hardy, low-light tolerant, and provides excellent hiding spots. Does not need to be planted in substrate -- attach to hardscape
• Anubias species: Extremely hardy, slow-growing plants. Anubias nana and Anubias barteri are popular choices. Attach to wood or rock; do not bury the rhizome
• Bucephalandra species: Beautiful, slow-growing rheophytes from Borneo. Shrimp love grazing on the biofilm that forms on their leaves
• Moss varieties (Flame Moss, Christmas Moss, Weeping Moss): All provide excellent shelter and foraging surface for shrimp. Create lush, natural-looking layouts
• Hornwort (Ceratophyllum demersum): A floating or loosely planted stem plant that absorbs excess nutrients and helps maintain water quality
• Marimo (Aegagropila linnaei): Shrimp enjoy picking at the surface of these green algae balls. Low maintenance and visually appealing

Quarantine Procedure for New Plants

Before introducing any new plant to a shrimp tank, follow this quarantine process:

• Rinse thoroughly: Remove the plant from its packaging and rinse under running tap water for several minutes to remove loose debris and surface chemicals
• Alum dip: Dissolve 1-2 tablespoons of potassium alum (found at pharmacies) in 1 liter of water. Soak plants for 2-3 hours, then rinse thoroughly. This helps remove snails and some pesticide residues
• Quarantine tank: Keep new plants in a separate container for 1-2 weeks. If shrimp or small snails placed in the quarantine water show no distress, the plants are likely safe
• Tissue culture plants: The safest option for shrimp tanks. These plants are grown in sterile laboratory conditions and are guaranteed pesticide-free. They are slightly more expensive but eliminate contamination risk entirely

Fertilization in Shrimp Tanks

Fertilizing planted shrimp tanks requires extra caution:

• Avoid copper-containing fertilizers: Check ingredient lists carefully. Many comprehensive plant fertilizers contain copper
• Use shrimp-safe fertilizers: Several brands market fertilizers specifically formulated for shrimp tanks. These omit copper and heavy metals
• Root tabs over liquid fertilizers: Root-feeding plants like Cryptocoryne benefit from root tabs inserted into the substrate, minimizing water column chemical exposure
• Go minimal: In shrimp-focused tanks, less fertilization is better. Shrimp waste provides some nutrients, and moderate plant growth is healthier than pushing for maximum growth
• CO2 supplementation: If using CO2 injection, monitor pH carefully. Rapid pH swings from CO2 fluctuation stress shrimp significantly

Water Quality Parameters for Shrimp

Maintaining stable water parameters is more important than hitting exact numbers:

• Temperature: 22-26°C for most popular shrimp species
• pH: 6.5-7.5 (avoid sudden changes)
• GH (General Hardness): 6-8 dGH for Neocaridina; 4-6 dGH for Caridina
• KH (Carbonate Hardness): 2-5 dKH
• TDS (Total Dissolved Solids): 150-250 ppm for Neocaridina; 100-150 ppm for Caridina
• Ammonia/Nitrite: Must be 0 at all times
• Nitrate: Below 20 ppm

When performing water changes, use dechlorinated water matched in temperature. Change no more than 10-20% at a time to avoid shocking the shrimp.
