Green Rili Shrimp carry the distinctive Rili pattern -- concentrated colour on the head carapace and rear abdomen with a reduced-pigmentation, semi-transparent midsection between them -- expressed in vivid green. The Rili pattern produces a visual effect unlike any solid-colour morph: the green head and tail appear to float independently, connected by the transparent midsection where the shrimp body shows through with minimal colour. In motion, the two coloured sections move through the water with the transparent midsection creating an animated, floating quality that draws attention differently from solid-colour shrimp. The specific intensity of the green colouration in the head and tail sections, and the degree of transparency in the midsection, both vary between individuals and improve with selective breeding -- the best specimens carry vivid, opaque green at the head and tail with a clearly transparent, almost colourless midsection. Hardy, beginner friendly, breeds freely in freshwater. Do not house with other Neocaridina colour variants.

What to Expect
Pattern, Colour and Behaviour
Vivid green head and tail contrasting with a transparent midsection -- the Rili pattern concentrates colour at the two ends of the body and leaves the midsection with reduced or absent pigmentation. In the best specimens the midsection is clearly transparent -- the internal organs faintly visible and the background substrate showing through the body tissue -- creating a clear visual separation between the coloured head and tail sections. The green in the coloured sections should be as vivid and opaque as possible; the midsection should be as transparent as possible for maximum pattern contrast.
Pattern clarity improves with selective breeding -- clear vs diffuse midsection -- the defining quality distinction between individual Green Rili shrimp is the clarity of the transition between coloured and transparent sections. In lower-quality individuals the colour fades gradually from head to midsection rather than transitioning sharply, producing a less defined pattern. In higher-quality individuals the boundary between green head/tail and transparent midsection is clear and relatively sharp, making the pattern read as more graphic and more intentional.
Transparent midsection creates a unique visual quality in motion -- when a Green Rili shrimp moves through the tank, the transparent midsection creates a floating-ends effect that draws the eye differently from a solid-colour shrimp -- the two green sections appear to move independently rather than as a single unit, and the movement of the transparent midsection against the background substrate creates a subtle shimmer that enhances the visual interest of each individual animal.
Dark substrate for maximum pattern visibility -- the transparent midsection of the Rili pattern only reads as transparent if the background visible through it is clearly darker than the coloured head and tail. Dark substrate directly behind and below the shrimp provides the contrast that makes the transparency apparent -- on pale substrate the midsection and the background merge and the pattern reads as a diffuse fade rather than a clear transparent window.
Hardy and beginner friendly -- full Neocaridina tolerance -- Green Rili carry the same broad parameter tolerance and robust constitution as all Neocaridina. The Rili pattern does not come with any increased care requirements.
How to Set It Up
Getting Started
1Dark substrate for maximum Rili pattern visibility -- black aquasoil or dark sand is essential for the transparent midsection to read clearly. Without dark substrate the pattern is substantially less visible.
2Stable Neocaridina parameters before introduction -- pH 7.0-7.4, GH 6-8, KH 3-5, temperature 72-75F. Confirm stability before introduction.
3Drip acclimate over 45-60 minutes -- float bag 15 minutes, drip at one drop per second for 45-60 minutes.
4Select clearest-pattern offspring as future breeders -- when offspring develop, identify individuals with the sharpest transition between coloured and transparent sections and the most vivid green in the coloured zones as breeding stock for the next generation.
Bonus TipGreen Rili shrimp in a tank with a moderate flow creating gentle current across the substrate -- just enough to create subtle water movement without stressing the shrimp -- makes the floating-ends effect of the Rili pattern most visible. The movement of the water against the transparent midsection creates a slight shimmer that is more visible in flowing water than in still conditions, and the swimming motion of actively moving shrimp in current emphasises the independent-floating quality of the coloured head and tail sections more than stationary shrimp grazing on substrate.
