General FAQ
How do you properly remineralise RO water for a Caridina cf. cantonensis tank?
You should always remineralise reverse osmosis water in a separate container using specific GH+ minerals before adding it to the aquarium to avoid sudden parameter fluctuations.
What is the ideal pH range for breeding Crystal Red shrimp successfully?
Crystal Red shrimp breed most effectively when the water pH is maintained in a slightly acidic range between 6.0 and 6.8.
Why is an active substrate necessary for keeping Bee shrimp species?
An active substrate is crucial because it acts as a buffer to keep the pH levels consistently below 7.0, which is vital for the health of sensitive Caridina species.
How often should a 20% water change be performed in a high-end shrimp colony?
In a well-maintained colony, a small water change of approximately 20% should be performed weekly to ensure water quality remains stable.
What specific GH level is recommended for Caridina cantonensis molting health?
For proper molting and shell development, a General Hardness (GH) level between 3 and 6 dGH is typically recommended.
Is it safe to use tap water for a Crystal Black shrimp aquarium?
You should never use tap water for Caridina shrimp because it often contains minerals and potential contaminants like copper that are deadly to them.
What is the maximum safe temperature for Caridina cf. cantonensis survival?
Temperatures should ideally stay below 74°F (23°C), as higher levels can stress the shrimp and reduce available oxygen.
Which type of filter is safest for protecting newborn shrimplets from suction?
A sponge filter or a filter equipped with a fine mesh guard is the safest option to prevent tiny shrimplets from being sucked into the intake.
How long does a female Bee shrimp carry her eggs before they hatch?
A female will carry her fertilised eggs under her tail for a period of roughly 3 to 4 weeks before the shrimplets hatch as mini versions of the adults.
What role do Indian Almond leaves play in a dwarf shrimp habitat?
Indian Almond leaves provide a surface for beneficial biofilm to grow and help naturally lower the water's pH as they decompose.
What is the ideal Total Dissolved Solids (TDS) range for Bee shrimp?
The recommended TDS range for maintaining healthy Bee shrimp is generally between 80 and 150 ppm.
Why is copper considered the most dangerous substance in a shrimp tank?
Copper is extremely toxic to invertebrates and even trace amounts can lead to a total colony collapse within hours.
How many Crystal Red shrimp should you start with to ensure a stable colony?
It is best to start with at least 10 to 15 shrimp to ensure a healthy mix of genders and encourage natural social behaviour.
Which moss species is best for providing hiding spots for molting shrimp?
Java Moss and Christmas Moss are highly recommended because their dense structures provide excellent refuge and grazing areas.
How can you tell the difference between a male and female Caridina shrimp?
Females are generally larger with a more rounded underbelly for carrying eggs, while males are slimmer and smaller.
What is the "White Ring of Death" in freshwater shrimp maintenance?
This term refers to a failed molting attempt where the shell splits but the shrimp cannot escape, often caused by improper GH or KH levels.
Why should you avoid mixing Neocaridina and Caridina shrimp in the same tank?
They are often incompatible because they require significantly different pH and water hardness levels to thrive and breed.
What is the best way to top up water lost to evaporation in a nano tank?
You should use pure RO water for top-ups to replace evaporated liquid without increasing the concentration of minerals in the tank.
How long is the typical lifespan of a well-cared-for Bee shrimp?
In a stable environment, these shrimp typically live for 1.5 to 2 years, though some may reach 3 years.
What is the recommended Carbonate Hardness (KH) level for Crystal Red shrimp?
The ideal KH level for these shrimp is extremely low, usually between 0 and 1 dKH, to allow the active substrate to maintain an acidic pH.
Should you remove shrimp exoskeletons from the tank after they molt?
No, you should leave the discarded shells in the tank as the shrimp will often eat them to reabsorb essential minerals like calcium.
What are the primary signs of stress in a Caridina cf. cantonensis colony?
Common signs of stress include loss of vibrant colour, lethargy, and a lack of grazing activity on the biofilm.
How do you prevent ammonia spikes when starting a new shrimp tank?
You must ensure the aquarium is fully cycled and matured before adding shrimp, as they are extremely sensitive to even trace amounts of ammonia.
Which vegetable is a safe supplementary food for dwarf shrimp?
Blanched organic spinach, courgette, or kale are excellent occasional treats that provide essential vitamins and minerals.
How do pheromones affect the behaviour of male shrimp after a female molts?
When a female molts and is ready to mate, she releases pheromones that cause the males to swim frantically around the tank in search of her.
What is the benefit of using a sponge pre-filter on a hang-on-back filter?
A pre-filter sponge prevents shrimplets from being trapped in the intake and provides an additional surface for them to graze on.
Why is it important to monitor Nitrate levels in a high-grade shrimp tank?
High Nitrates can inhibit growth and reproduction, so levels should ideally be kept below 10 ppm through regular maintenance.
What is the purpose of adding Bacter AE or similar powdered foods to the tank?
These powdered foods promote the growth of natural biofilm, which is the primary and most important food source for newborn shrimplets.
Can Crystal Red shrimp live with nano fish like Ember Tetras?
Yes, they can live with peaceful nano fish, though there is always a small risk that the fish might eat the smallest shrimplets.
What should you do if you notice a dead shrimp in your aquarium?
You must remove dead shrimp immediately to prevent a spike in ammonia that could harm the rest of the sensitive colony.
