Bloody Mary Shrimp: Neocaridina davidi
An intense blood-red Neocaridina whose colour sits in the shell rather than the flesh, so it holds under bright light where cherry shrimp can wash out.
Also known as: Bloody Mary Neocaridina · Neocaridina davidi var. Bloody Mary
Bloody Mary Shrimp
An intense blood-red Neocaridina whose colour sits in the shell rather than the flesh, so it holds under bright light where cherry shrimp can wash out.
Natural Habitat & Origin
A selectively bred line of Neocaridina davidi from Taiwan and eastern China.
Care Requirements
Keep Bloody Mary Shrimp at 18-28°C with a pH of 6.5-8.0. Undemanding within a broad range. Avoid copper entirely and keep parameters steady rather than chasing exact numbers.
Use the Aquarium Tracker to log these parameters against your own readings — it flags a drift before it becomes a problem.
Diet & Feeding
Biofilm and algae, supplemented with blanched vegetables and prepared shrimp foods.
Behaviour & Temperament
Peaceful, busy and social. Colour intensifies with age and holds well under strong lighting.
Tank Mates
Species tank or the smallest peaceful fish. Assume anything with a mouth large enough will predate them.
Breeding
Breeds prolifically in fresh water with no special conditions.
Colour lines and breeding true
This is a selectively bred line of Neocaridina davidi — the same species as the cherry shrimp, and care is identical. Mixing colour lines in one tank produces offspring that revert toward wild brown within a few generations, so keep lines separate if you want the colour to hold.
Common Health Issues
Copper toxicity and moulting problems are the main risks.
