What to Expect with Color

Dark Bloody Mary Shrimp are known for their deep wine red to maroon coloration created by strong sub-surface pigmentation rather than just surface shell coloration. Their exoskeleton can appear glossy or even glass-like under bright light with the internal tissues creating a bold saturated tone.

Unlike Cherry or Fire Red lines which rely heavily on surface pigment these shrimp often have a transparent outer layer with dense red underneath. This produces uniform color coverage including legs antennae and tail which helps distinguish them from regular red morphs.

Color can intensify with age proper diet and stable conditions. Females generally show deeper coverage and a larger more vivid profile while males may appear slightly slimmer with lighter intensity though still maintaining strong saturation. Juveniles typically begin darker than other red morph fry and continue to deepen through multiple molts.

General Care Behavior and Tank Conditions

These shrimp share all the hardy traits of Neocaridina davidi. A mature aquarium rich in biofilm moss and gentle hiding areas supports healthy grazing and confident behavior. They are peaceful algae grazers that help maintain natural balance while adding striking visual contrast to aquascapes.

Good diet supports deep coloration. Foods containing spirulina astaxanthin and beta glucans encourage pigment development and maintain proper shell formation. Avoid sudden changes in water chemistry as stress can temporarily reduce visible color intensity.

Bonus Tip

To preserve the darkest genetics avoid mixing with other red Neocaridina lines. Select the deepest most uniform red individuals each generation to maintain the highest grade presentation.
