description Blue Rili Shrimp Overview
The Blue Rili Shrimp is a selectively bred color variant of Neocaridina davidi, a freshwater shrimp species in the family Atyidae. The Rili pattern refers to a distinctive body coloration featuring opaque or solid-colored head and tail sections with a translucent middle portion. This blue variant was developed by crossing blue coloration lines with existing Rili-patterned shrimp through selective breeding. Neocaridina davidi morphs are among the most commonly kept freshwater ornamental shrimp in the aquarium hobby due to their hardiness and variety of colors.
help Blue Rili Shrimp FAQ
What is a Blue Rili Shrimp?
The Blue Rili Shrimp is a selectively bred color morph of the hardy freshwater species Neocaridina davidi. It is characterized by a striking pattern of deep blue coloration on its head and tail, contrasted by a completely clear, translucent middle section. They are highly popular in the aquarium hobby due to their vibrant contrast.
How were Blue Rili Shrimp created?
This specific morph was created by selectively crossing Blue Velvet shrimp with Rili pattern shrimp (which originally have red or black markings). Breeders isolated the genetic traits for both the blue pigmentation and the Rili 'clear band' mutation. Through generations of careful breeding, they stabilized the unique blue and transparent combination.
What water parameters do Blue Rili Shrimp need?
Like all Neocaridina davidi varieties, Blue Rili shrimp are incredibly adaptable and thrive in standard freshwater aquarium temperatures between 64°F and 76°F. They prefer a pH range of 6.5 to 7.5 and do well in moderately hard water. Their extreme hardiness makes them an ideal choice for beginner shrimp keepers.
Will Blue Rili Shrimp breed with Red Cherry shrimp?
Yes, because they belong to the exact same species (Neocaridina davidi), Blue Rili shrimp will readily interbreed with Red Cherry or standard Rili shrimp. If they interbreed, the offspring will typically revert to a wild, brownish-clear coloration over several generations. Aquarium keepers usually isolate specific color morphs to maintain the pure blue Rili pattern.
