Dwarf shrimps have become increasingly popular as ornamental pets among aquarium enthusiasts. Their vibrant colour, tiny size, and unique characteristics make them prized additions to your freshwater aquarium. However, they also require specific care and habitat considerations to thrive.
Types of Dwarf Shrimps
Neocaridina Shrimp
Neocaridina shrimps are a popular choice for both beginners and experienced shrimp keepers because they are known for their hardiness and vibrant colour. These species come in different colour shades, from the bloody mary cherry reds to the heavenly hue of blue dreams, and more, that are sure to give your aquarium a pop. Neocaridina shrimps thrive better in stable tank conditions that have abundant hiding spots and vegetation.
Caridina Shrimp
Caridina shrimps, such as crystal red shrimp and bee shrimp, are prized for their unique patterns and behaviours. These species require specific water parameters, including pH and hardness, to thrive. Keeping these species of dwarf shrimps requires careful attention to water quality because they are more sensitive than Neocaridina shrimps.
Setting Up a Dwarf Shrimp Tank
Creating the perfect environment for dwarf shrimps is important to ensure that they survive and stay in their healthiest conditions. Setting up their freshwater tanks involves several key considerations:
Tank size and setup
The size of the tank is crucial in keeping your dwarf shrimps healthy. When choosing the right tank size, you must consider the number of shrimps you plan to keep and the space for them to swim around, forage, and moult comfortably. Overcrowding can lead to stress and territorial issues among shrimps. Additionally, having ample space allows for proper water circulation and maintenance of water parameters.
Substrate and plants
Dwarf shrimps like to sift through the substrate to find their food, thus, selecting the appropriate substrate, such as fine sand or gravel, is important. A fine substrate prevents injury to their delicate bodies. Additionally, live aquarium plants not only enhance the visual appeal of the tank but also serve functional purposes. These plants serve as hiding spots for dwarf shrimps, reduce stress by mimicking their natural habitat, and help maintain water quality through oxygen production and nitrate absorption.
Filtration and water parameters
Strong water flow can harm dwarf shrimps. By installing a gentle filtration system suitable for shrimp tanks, injuries can be prevented. Consider using sponge filters or low-flow filters that provide adequate filtration without creating strong currents. In addition, water parameters must be optimized and maintained. Important water parameters to manage are temperature (ideally around 72-78°F), pH (typically neutral to slightly acidic), ammonia, nitrite, and nitrate levels. Changes in water parameters can stress shrimps and compromise their health.
Cycling the tank
Before your aquarium is ready to house your cute and colourful dwarf shrimps, it must undergo cycling. Cycling is a process that involves establishing beneficial bacteria that break down harmful ammonia and nitrites into less toxic substances. This process ensures a stable and healthy environment for shrimps to thrive. To kickstart the cycling process, ammonia sources like fish food or liquid ammonia are added to the tank. Once the ammonia and nitrite levels reach zero, the tank is now ready for shrimp keeping.
Care and Maintenance for Dwarf Shrimps
Feeding requirements
Dwarf shrimps have diverse nutritional needs, which means it’s crucial to offer them a variety of foods to keep them healthy and happy. They are typically fed with specialized shrimp pellets or granules as their main diet and supplemented with yummy blanched veggies like zucchini, spinach, or cucumber for essential vitamins and fibre. Once in a while, they also have bloodworms or brine shrimp for additional protein.
Water quality management
The optimization of the water parameters of the aquarium is crucial in maintaining the well-being of your dwarf shrimps. To monitor these important parameters, reliable test kits should be used. Partial water changes (around 10-20% weekly) using dechlorinated water are also required to remove accumulated feeds and feces and maintain water quality. Sudden changes in water parameters are dangerous because these would stress the dwarf shrimps leading to health issues, and in worse cases, would even cause death.
Common Issues
Algae Overgrowth
Algae overgrowth is caused by high levels of nutrients in the water and prolonged light exposure. Too much algae can release toxins, deplete oxygen levels, and make the tank look less appealing. To avoid this common issue in dwarf shrimp keeping:
- Gently remove excess algae from tank surfaces, decorations, and glass using algae scrapers or brushes.
- Consider using a timer for consistent lighting schedules to maintain a proper balance of light duration and intensity.
- Add algae-eating organisms like snails or certain fish species (e.g., Siamese algae eaters) to help control algae naturally.
- Avoid overfeeding to also avoid the buildup of nutrients in the water. Remove uneaten food promptly.
Tank Hygiene
Proper tank hygiene is essential for the health and well-being of your shrimp. To maintain tank hygiene:
- Clean debris and organic waste from the substrate with a gravel vacuum whenever conducting water changes.
- Wipe down tank surfaces, equipment, and decorations to remove dirt, algae, and biofilm.
- Trim live plants to prevent overcrowding and also keep them healthy.
- Check your filters for efficient water filtration and circulation
Signs of Diseases in Dwarf Shrimps
Dwarf shrimps are also susceptible to health issues and these can be seen in the signs and symptoms they exhibit. Common shrimp diseases include bacterial infections and moulting problems:
Bacterial infections
Symptoms of bacterial infections are lethargic behaviour, abnormal swimming patterns, cloudy or discoloured exoskeletons, and loss of appetite. When these are present in the shrimp, quarantine them immediately to avoid spreading the infection to other healthy shrimps. Also, consider treating the quarantine shrimps with antibiotics under the guidance of veterinarians or knowledgeable shrimp keepers.
Moulting
Moulting is a normal reaction of shrimps due to stress, changes in water parameters, and insufficient diet. Signs of moulting problems include failed moults (shrimp stuck in old shells), difficulty shedding, or shell deformities. To support healthy moulting cycles, maintain optimal levels of water parameters, feed the shrimps with nutrient-rich diets, and provide ample hiding spots and moulting-friendly surfaces.
Benefits of Keeping Dwarf Shrimps
Natural algae control: Innate Tank Cleaners
Dwarf shrimps eat algae naturally and this helps in keeping your aquarium clean and free from algae overgrowth. Their constant grazing on algae-covered surfaces promotes a healthier aquatic environment for both shrimps and other tank inhabitants.
Compatibility: Peaceful Coexistence
Dwarf shrimps can coexist peacefully with other fish species that are not aggressive and not predatory. However, keeping them in tanks with significantly bigger or more aggressive fish can result in them being hurt or eaten. Choose tankmates that share similar water parameter requirements and temperament to ensure compatibility.
Aesthetic appeal: Colourful Appearance and Intriguing Behaviours
Dwarf shrimps are small and colourful and they exhibit intriguing movements. Their natural behaviours, such as moulting, foraging, and social interactions, give a captivating and visually appealing element to your ornamental aquarium. Simply observing them gives us a delightful feeling and it would make us enjoy and appreciate them.
