Are you looking to set up a shrimp-only nano tank? These small aquariums are perfect for hobbyists who love vibrant and active shrimp species. Whether you’re a beginner or an experienced aquarist, this guide will help you create the ideal nano tank for your shrimp.

Why Choose a Shrimp-Only Nano Tank?

Low Maintenance: Small tanks require less upkeep compared to larger aquariums.
Aesthetic Appeal: Shrimp are colorful and fascinating to watch.
Space-Saving: Ideal for small homes, offices, and apartments.
Breeding Potential: A well-maintained shrimp tank can lead to a thriving colony.

Step 1: Choosing the Right Tank Size

A nano tank typically ranges from 5 to 10 gallons, but a 10-gallon tank is ideal for stability. Larger tanks help maintain consistent water parameters, reducing stress on shrimp.

Step 2: Selecting the Best Shrimp Species

Not all shrimp are suitable for nano tanks. Here are some of the best options:

Neocaridina Shrimp (Cherry Shrimp, Blue Dream, Yellow Shrimp) – Hardy and beginner-friendly.
Caridina Shrimp (Crystal Red, Crystal Black, Taiwan Bee) – More delicate, requiring soft water.
Amano Shrimp – Great algae eaters but require a larger space.

Step 3: Setting Up the Tank

1. Substrate Selection

Active Substrate (Caridina Shrimp) – Helps maintain soft, acidic water.
Inert Substrate (Neocaridina Shrimp) – Gravel or sand for neutral pH levels.

2. Filtration System

Sponge Filters – Ideal as they provide gentle filtration and won’t suck up baby shrimp.
Hang-on-Back (HOB) Filters – Suitable with a sponge pre-filter attachment.

3. Heater and Temperature Control

Maintain a temperature of 72°F to 78°F (22°C - 26°C).
Use a reliable heater with a thermostat for stable conditions.

4. Lighting

Low to moderate lighting is best to prevent excessive algae growth.
Use LED lights with a timer (8-10 hours daily).

5. Adding Plants and Decorations

Live plants like Java Moss, Anubias, and Bucephalandra provide hiding spots and biofilm for shrimp.
Driftwood and rocks create a natural environment.

Step 4: Cycling the Tank

Before adding shrimp, cycle your tank for 4-6 weeks to establish beneficial bacteria. Use:

Ammonia Source (fish food or liquid ammonia)
Seachem Stability or API Quick Start to speed up the process.
Test water parameters before adding shrimp.

Step 5: Water Parameters and Maintenance

Optimal Water Conditions

pH: 6.5 - 7.5 (Neocaridina) / 5.8 - 6.8 (Caridina)
GH (General Hardness): 6-8 dGH
KH (Carbonate Hardness): 1-4 dKH
TDS (Total Dissolved Solids): 150-250 ppm
Ammonia & Nitrite: 0 ppm
Nitrate: Below 20 ppm

Regular Maintenance

Weekly Water Changes (15-20%) with dechlorinated water.
Use shrimp-safe water conditioners like Seachem Prime.
Remove uneaten food to prevent ammonia spikes.

Step 6: Feeding and Care

Shrimp are scavengers and thrive on a variety of foods:

High-quality shrimp pellets and blanched vegetables (zucchini, spinach).
Biofilm and algae are natural food sources.
Supplement with calcium-rich foods for strong shells.

Step 7: Breeding Shrimp Successfully

Keep stable water conditions.
Provide plenty of hiding spots for baby shrimp.
Feed protein-rich foods occasionally to support breeding.

Setting up a shrimp-only nano tank is a rewarding experience that enhances any space with vibrant colors and movement. With the right setup, your shrimp colony will thrive for years.
