About Blue Jelly Shrimp

Blue Jelly Shrimp are one of the most unique-looking Neocaridina varieties, featuring a highly translucent body with a delicate blue tint that gives them a jelly-like or glass-like appearance. Their semi-transparent nature allows you to observe their internal structures, including the digestive system and, in mature females, the eggs developing in their saddle. This transparency makes them fascinating to watch and study. The Blue Jelly variety sits somewhere between the clear wild-type Neocaridina and the more intensely colored Blue Velvet or Blue Dream varieties. Their subtle coloration emerged from crossbreeding various blue lines, and they haven't been as heavily selected for color intensity as other blue varieties. This gives them their characteristic see-through appearance with just a hint of blue pigmentation. One interesting trait of Blue Jelly Shrimp is that they may occasionally display red or pink spots, particularly around the head, eyes, or tail region. This is not a defect but rather a genetic expression that some hobbyists find attractive, as it creates a unique color combination. Like all Neocaridina, Blue Jelly Shrimp are hardy, adaptable, and excellent for beginners who want an interesting conversation piece in their aquarium.

Water Parameters for Blue Jelly Shrimp

Maintaining stable water parameters is crucial for the health and coloration of Blue Jelly Shrimp. As a Neocaridina species, they are relatively hardy and can tolerate a wider range of parameters than Caridina species.

Parameter Range Optimal
TDS 150-300 ppm 180-250 ppm
GH 4-14 dGH 6-8 dGH
KH 2-8 dKH 2-5 dKH
pH 6.5-8 6.8-7.5
Temperature 64-82°F (18-28°C) 68-75°F

Tank Setup for Blue Jelly Shrimp

  • Minimum 5 gallon tank recommended
  • Dark substrate helps their subtle blue color stand out
  • Dense planting provides security and grazing surfaces
  • Sponge filter for gentle flow and additional biofilm
  • Good lighting helps display their unique translucent quality

Care Tips for Blue Jelly Shrimp

  • Maintain stable water parameters for best health
  • Keep in groups of at least 10 for natural behavior
  • Their transparency makes them harder to spot - take care when cleaning
  • Provide plenty of plants and hiding spots
  • Their translucent nature makes internal health issues more visible
  • Avoid copper-based medications
  • Small weekly water changes of 10-15% are ideal

Feeding Blue Jelly Shrimp

  • Feed quality shrimp foods 2-3 times weekly
  • Biofilm is essential and should be their main food source
  • Blanched vegetables provide variety
  • Their transparent gut makes it easy to see when they've eaten
  • Remove uneaten food within a few hours

Breeding Blue Jelly Shrimp

Difficulty
easy
Clutch Size
20-30 eggs
Gestation
28-35 days
Special Requirements
Blue Jelly Shrimp may produce offspring with varying degrees of blue intensity and occasional red spots. Selective breeding over generations can help stabilize the desired appearance.
  • Offspring may vary in blue intensity and transparency
  • Some babies may show more or less red spotting
  • Females carry 20-30 eggs visible through their transparent body
  • Shrimplets are fully independent at birth
  • Selective breeding can help achieve more consistent coloration

Common Problems with Blue Jelly Shrimp

  • They can be hard to see in tanks - use care when doing maintenance
  • Color consistency varies due to less selective breeding
  • Red spots are normal genetic expression, not disease
  • Their transparency makes internal parasites or issues more visible
  • May produce offspring with varying color intensities
