How to Keep Shrimps in an Aquarium: A Complete Guide
Keeping shrimps in an aquarium is a rewarding experience for both beginners and expert aquarists. These small, vibrant creatures not only add beauty to your tank but also help maintain a clean ecosystem by eating algae and organic waste. In this guide, we’ll cover everything you need to know about keeping freshwater shrimp in an aquarium, including tank setup, water parameters, diet, and common shrimp species.
Choosing the Right Aquarium for Shrimp
The first step to successfully keeping shrimp in an aquarium is selecting the right tank. While some shrimp species can thrive in nano tanks as small as 5 gallons, it is recommended to go for a 10-gallon tank or larger to ensure better stability in water parameters. A well-established shrimp tank helps prevent sudden changes that can be harmful to these delicate creatures.
Key considerations for a shrimp tank:
Tank Size: A minimum of 5 gallons for small shrimp colonies, but 10 gallons or more is ideal.
Substrate: Use a fine, soft substrate like shrimp soil or sand to encourage natural behavior and support plant growth.
Filtration: A sponge filter is ideal as it prevents shrimp from being sucked into the filter.
Plants & Hiding Spots: Live plants like Java moss, Anubias, and floating plants provide shelter and improve water quality.
Water Parameters for Freshwater Shrimp
Maintaining stable water parameters is crucial for shrimp health. Shrimp are highly sensitive to ammonia and nitrites, so regular water testing is essential.
Temperature: 72-78°F (22-26°C)
pH Level: 6.5-7.5
GH (General Hardness): 4-8 dGH
KH (Carbonate Hardness): 1-4 dKH
Ammonia & Nitrite: 0 ppm (any level above 0 can be toxic)
Nitrate: Below 20 ppm
It is important to cycle your aquarium before adding shrimp. The nitrogen cycle should be fully established to prevent ammonia spikes, which are lethal to shrimp.
Best Shrimp Species for Aquariums
There are various shrimp species to choose from, each with different care requirements. Some of the most popular and beginner-friendly shrimp include:
Neocaridina Shrimp (Cherry Shrimp): Hardy and available in various colors such as red, yellow, and blue.
Caridina Shrimp (Crystal Red/Black Shrimp): More delicate and require specific water parameters.
Amano Shrimp: Great algae eaters and ideal for planted tanks.
Ghost Shrimp: Transparent shrimp that are easy to care for and affordable.
Feeding Aquarium Shrimp
Shrimp are omnivores and require a balanced diet for optimal health. They primarily feed on biofilm, algae, and leftover food in the tank.
Best food options for shrimp:
High-quality shrimp pellets
Blanched vegetables (zucchini, spinach, cucumber)
Algae wafers
Indian almond leaves (improves water quality and provides natural food source)
Protein-rich food (once a week) like bloodworms
Avoid overfeeding as it can lead to water quality issues. Feed small amounts and remove any uneaten food within a few hours.
Tank Mates for Shrimp
Choosing the right tank mates is crucial to ensure shrimp safety. Some fish species may see shrimp as food, so avoid keeping them with aggressive fish.
Ideal shrimp tank mates:
Small, peaceful fish like neon tetras, guppies, and endlers
Snails (Nerite, Mystery, or Ramshorn)
Other dwarf shrimp species
Fish to avoid:
Betta fish
Cichlids
Goldfish
Large catfish
Breeding Shrimp in an Aquarium
Shrimp breeding is relatively easy if the conditions are right. Neocaridina shrimp, like Cherry Shrimp, are especially prolific breeders. Provide plenty of hiding spots and ensure stable water conditions to encourage reproduction. A female shrimp carries eggs under her abdomen for about 3-4 weeks before they hatch into miniature shrimp.
Common Problems and Solutions
1. Shrimp Molting Issues
Solution: Ensure proper mineral balance by adding calcium-rich foods or cuttlebone to the tank.
2. Shrimp Not Breeding
Solution: Check water parameters, ensure a stable environment, and feed a varied diet.
3. Sudden Deaths
Solution: Test water quality, avoid copper-based medications, and perform gradual water changes.
Final Thoughts
Keeping freshwater shrimp in an aquarium can be a fascinating and rewarding hobby. By setting up a proper shrimp tank, maintaining stable water parameters, and providing a balanced diet, you can ensure a thriving shrimp colony. Whether you choose Cherry Shrimp, Amano Shrimp, or Crystal Red Shrimp, following these guidelines will help you enjoy a beautiful and healthy shrimp aquarium for years to come.
