Natural habitat
Caridina simoni is widespread in Sri Lanka and is also reported from Tamil Nadu, India. It lives in rivers, streams, ponds, lakes and reservoirs from the lowlands up to about 700 m, usually in shallow, slow margins among plants, algae and debris.
Where they are found
The species has been documented in varying freshwater environments, from clear streams to murky lakes, showcasing its adaptability to different ecological conditions in its native range.
Aquarium care
To successfully keep this species, it's essential to provide a tank environment with ample vegetation and structural cover. A minimum tank size of 30 liters is recommended, complete with fine sand substrate covered by Indian Almond leaves to regulate water quality.
Feeding
A small grazer of biofilm, algae and detritus. Supplement with shrimp pellets, blanched vegetables and leaf litter, and feed sparingly.
Compatibility
These shrimp are small and peaceful, making them ideal for community tanks with similarly small and gentle fish like Boraras species and Pygmy Corydoras. They should not be kept with larger or aggressive fish that may pose a threat to their safety.
Breeding
Breeding occurs when females carry fertilized eggs (berried) under their tails, eventually releasing larvae into the water column. Ensure stable water conditions to promote successful breeding.
