Aquarium Setup Neocaridina Davidi ‘Blue Jelly’
Aquarium Filtration
Gentle filtration is recommended, with sponge filters being ideal to protect shrimp and support beneficial bacterial colonies.
Aquarium Plants
Dense planting with mosses such as Java Moss and fine-leaved plants provides grazing surfaces, shelter, and protection for juveniles.
Aquarium Lighting
Moderate lighting encourages plant growth and biofilm development, both essential for shrimp health.
Aquarium Heating
Maintain stable temperatures between 20–26 °C. While this species is tolerant, sudden fluctuations should be avoided.
Aquarium Substrate
Inert substrates such as fine gravel or sand are suitable, though darker substrates can enhance the shrimp’s blue coloration.
