Blue Diamond Shrimp
Deep, opaque sapphire blue — the most striking Neocaridina line in the hobby.
Solid, saturated blue Neocaridina bred for opaque color that carries all the way through the body rather than fading to translucent. Every bit as hardy as a cherry shrimp: they graze biofilm around the clock, breed readily in stable water, and forgive beginner mistakes. Sold as individual young adults already colored up and eating.

What it needs to thrive
- Lighting
- Any — color reads best against dark substrate under warm, moderate lighting.
- Flow
- Gentle to moderate. Sponge filters or pre-filtered intakes only so juveniles are never drawn in.
- Feeding
- Biofilm and algae grazers. Supplement 2–3× weekly with a quality shrimp pellet, blanched vegetables, or botanicals.
- Temperament
- Peaceful — keep with nano fish only. Never expose to copper-based medications.
- Difficulty
- Beginner
- Ideal Tank Size
- 5 gallons and up, fully cycled and mature.
- Water Parameters
- 68–78°F · pH 6.8–7.6 · GH 6–8 · KH 2–5 · TDS 150–250 · 0 ammonia / 0 nitrite / <20 nitrate · copper-free
Anywhere in a mature planted tank. Dark substrate, moss, and botanicals make the blue read deepest and give juveniles cover.
Completely peaceful. Keep only one Neocaridina color line per tank — mixed morphs revert to wild brown within a few generations.
Quarantine, dip, and acclimation
Quarantine
Hold all new fish in a bare-bottom 10–20 gallon QT for a minimum of 4 weeks. Observe for flashing, clamped fins, white spots, or breathing changes. Treat preventatively with copper (1.75–2.5 ppm chelated) or tank-transfer method for ich, plus a praziquantel course for flukes. Invertebrates and corals skip QT but go through dip and observation instead.
Recommended coral dip
For every new coral: a 5–10 minute bath in your reef-safe dip of choice (Bayer Complete, CoralRx, or Reef Primer) following label dosage, followed by two clean saltwater rinses. Inspect plugs and bases for flatworms, pyramid snails, and eggs — remove or refrag onto clean plugs before placing in display.
Acclimation
Float sealed bags in your QT or display for 15 minutes to match temperature. Then drip acclimate at 2–4 drops per second for 45–60 minutes until volume has tripled. Net livestock into the tank — never pour shipping water in. Dim the lights for the first 24 hours to reduce stress.
