Bloody Mary Shrimp are the standard expression of the Bloody Mary Neocaridina line -- a vivid, warm red body colour that carries enough translucency that the internal organs are partially visible through the body tissue, giving each animal a layered, lit-from-within quality that is distinct from the denser, more opaque wine-red of Dark Bloody Mary. Where Dark Bloody Mary is selected specifically toward full opacity and the deepest possible colour depth, standard Bloody Mary retains the vivid, warm-toned red and the partial transparency that characterised the line before intensive opacity selection. The colour reads as warm and clearly red rather than wine-like or cool -- a vivid, immediately attractive red that is the entry point to the Bloody Mary line and the reference against which the Dark grade is measured. Hardy, beginner friendly, breeds freely in freshwater. Do not house with other Neocaridina colour variants to prevent colour reversion in offspring.

What to Expect
Colour, Translucency and Behaviour
Vivid warm red with partial translucency -- distinct from Dark Bloody Mary -- the colour is unmistakably red and clearly warm in tone -- neither the cooler wine-red of Dark Bloody Mary nor the orange-inflected red of Blood Orange, but the clear, warm, vivid red that the line is named for. The partial translucency means the internal organs are visible through the body tissue in good light, giving each shrimp a depth and layered quality that fully opaque morphs do not have. This translucency is a characteristic of the standard grade, not a quality deficiency.
The foundation of the Bloody Mary line -- reference point for all grades -- Bloody Mary is the original and most widely kept expression of the line. Dark Bloody Mary is a subsequent selective development toward greater opacity -- a premium on the same base colour. Both are attractive and clearly distinct when seen side by side, with Bloody Mary reading as warmer and brighter and Dark Bloody Mary reading as deeper and more wine-toned.
Colour deepens with each generation in stable conditions -- like all Neocaridina, colour saturation and opacity improve progressively with each generation produced under stable, well-maintained parameters. A Bloody Mary colony kept well over multiple generations moves progressively toward deeper, more opaque red -- the line between standard Bloody Mary and Dark Bloody Mary is not fixed but a continuum that shifts with the selection pressure applied across breeding generations.
Dark substrate enhances colour visibility and warmth -- the vivid warm red of Bloody Mary reads most clearly against dark substrate where the contrast is maximum. On pale substrate the red reads as less saturated and the warmth of the tone is less apparent.
Hardy and beginner friendly -- broad Neocaridina tolerance -- Bloody Mary carry the full broad parameter tolerance of all Neocaridina and are fully appropriate for beginner keepers. Dense moss, consistent feeding, and stable parameters produce well-coloured, actively breeding colonies within the first two to three months of establishment.
How to Set It Up
Getting Started
1Dark substrate and stable parameters before introduction -- black aquasoil or dark sand, pH 7.0-7.4, GH 6-8, KH 3-5, temperature 72-75F. Confirm stability for one week before introduction.
2Drip acclimate over 45-60 minutes -- float bag 15 minutes, drip at one drop per second for 45-60 minutes before release.
3Dense moss and biofilm surfaces from the start -- Java Moss, Christmas Moss, or Flame Moss provides biofilm foraging and shrimplet shelter from the first breeding cycle.
4Select deepest-coloured offspring to progressively deepen the line -- when offspring develop, identify the most opaque, most vividly red individuals as breeding stock. Consistent selection across multiple generations moves the colony toward the Dark Bloody Mary grade over time.
Bonus TipBloody Mary alongside Blue Dream or Blue Diamond Neocaridina in adjacent tanks creates the most classic complementary warm-cool pairing in the Neocaridina catalog. The warm vivid red of Bloody Mary against the cool blue of Blue Dream on dark substrate reads as a considered, maximum-contrast colour pairing -- the two colours are spectrally opposite in the warm-cool dimension and each makes the other appear more vivid by comparison.
