Choosing Neocaridina (Cherry Shrimp) Colours

How Bloody Mary, Blue Diamond, and mixed-colour Neocaridina colonies fit different aquarium goals.

Key takeaway

Choose one established colour line for consistent offspring, or embrace variation when a mixed colony is the point.

01

Begin with the colony you want to see

Neocaridina shrimp are active grazers with a wide range of established colours. Bloody Mary shrimp bring deep translucent crimson tones; Blue Diamond shrimp bring saturated navy-to-cobalt colour. High-quality culls offer healthy, varied appearances at a more accessible price.

Colour is only one part of the choice. Start with livestock suited to a mature aquarium and a water routine you can repeat. Our locally bred Neocaridina are raised in Toronto water, and source-water details are confirmed with each order.

02

Keep colour lines separate for consistency

Different Neocaridina colours can breed together. Over generations, their offspring may become less predictable and can trend toward wild-type brown, clear, or patterned appearances.

If a uniform red or blue colony is the goal, keep one colour line per aquarium and avoid moving shrimp, plants, or filter media between colonies without checking for hidden juveniles.

03

Use a mixed colony intentionally

A mixed-colour Neocaridina aquarium can be lively and visually varied. It works best when you enjoy genetic surprises and do not expect every generation to match the parents.

Culls are also a practical choice for planted community tanks, first colonies, and aquariums where grazing behaviour matters more than a uniform show colour.

04

Plan a sensible starting group

A larger starting group gives a new colony more genetic diversity and a better chance of including both sexes. The right number still depends on aquarium volume, maturity, existing livestock, and available grazing surface.

Avoid treating a pack size as a shortcut around tank readiness. A stable aquarium with a modest group is safer than an immature aquarium with a large one.

  • Choose a single shrimp for an established display or addition
  • Choose a colony pack when breeding and long-term growth are goals
  • Confirm current stock, source water, and acclimation advice before pickup
05

Evaluate quality beyond colour

Look for normal grazing, balanced movement, intact antennae and legs, and a seller who can explain how the shrimp were kept. Representative product photos show the line, but natural shade, pattern, age, and body form vary.

The strongest choice is the colony that fits your aquarium and expectations—not simply the darkest individual in a photograph.
