Demon Chocolate | Orange Eyes Genetic

A dark brown shrimp with bright orange eyes.

The orange eyes are there from day one. The brown body arrives lighter and darkens as they grow — and that dark shell is what makes the eyes stand out.

One price, no grades. The eye colour is the rare part, and it is either there or it is not.

Neocaridina — the easier of our two shrimp families, hardy and quick to breed, and a good first shrimp. Numbers in the FAQ.

The Chocolate is a dark brown Neocaridina — the line many of the darker cherry colours were bred out of. The Demon Chocolate adds the orange-eye (“Demon”, OE) mutation: the eye lacks its dark pigment and shows orange instead. The trait is recessive, so it takes deliberate line-breeding to hold in a colony. Orange-eyed Neocaridina were first stabilised in Germany by the breeder Michael Häsler and reached the wider hobby around 2025; a true one keeps a small dark dot in the centre of the eye.

About the photo. The shrimp pictured is one of the best-looking adults from the batch. The eye is there from birth; the brown shell thickens and darkens with each moult, which is what makes the eye stand out on an adult.

Two traits, on two different schedules:

• The orange eye: Fixed from birth and does not change with age or water. It is the rare part of this shrimp.
• The brown builds with age: Young Neocaridina are naturally more see-through. The chocolate thickens and darkens with each moult until the shell is solid dark brown at full size.

The orange eye is either there or it is not — a fixed trait, not a gradient — and the brown body follows the usual Neocaridina maturity curve. So Demon Chocolates are one grade, one price: robust unsexed juveniles carrying the orange-eye trait from our line.
