For Neocaridina shrimp keepers

Your first shrimp tank, minus the guesswork.

Shrim takes you from an empty tank to a breeding colony of cherries, blues, yellows or any Neocaridina color. It tells you what to buy, when the tank is ready, and what every water reading means for your shrimp.

    Troubleshoot in seconds

    Tap what you're seeing to get the likely cause and the fix.

Every color, one species

Cherry, blue, yellow, green and the rest.

All Neocaridina colors share the same water and care. Shrim adds color-specific guidance for breeding and culling, so your line stays true.

Why shrimp die

Most losses trace back to three things.

Shrimp are far more sensitive than fish. Shrim keeps an eye on all three so you can catch problems early.

An unstable or uncycled tank

Shrimp added before ammonia and nitrite hold at zero, or big swings from large water changes.

Shrim tracks your cycle and says when the tank is ready. It reminds you to change 10 to 15 percent weekly, not more.

A mineral problem

GH too low and shrimp die mid-molt. Too high and the old shell won't come off.

Shrim flags GH, KH and TDS outside the target range and explains how to correct them slowly.

A toxin

Chloramine in tap water, copper from pipes or fish meds, pesticides on new plants.

Shrim's troubleshooter matches what you see, like deaths right after a water change, to the likely cause and the fix.

How it works

Set up in two minutes, then a minute a day.

  1. Answer four questions

    Your experience, where your tank is today, its size, and your water source. Shrim builds a plan for that exact starting point.

  2. Follow your journey

    Seven milestones, from gathering gear to keeping your color line true. Each one tells you the next thing to do.

  3. Log and relax

    Enter a water test or a headcount in under a minute. Shrim checks it, charts it, and schedules what's due next.

What's inside

Everything a colony needs, in your pocket.

Nine short lessons

Temperature, water chemistry, toxins, minerals, feeding, acclimation and breeding. Read the right ones first.

Water charts

Eight parameters charted against their target band, so a slow drift shows up before it hurts.

Care reminders

Daily, weekly and monthly jobs that reschedule themselves, plus a feeding tracker that knows when to skip.

Colony log and photos

Headcounts, berried females and shrimplets, with photos to compare color before you cull.

Troubleshooter

Tap what you're seeing and get the likely cause and the fix, plus a drip acclimation timer.

More than one tank

Keep a main colony, a cull tank and a grow-out tank side by side, each with its own logs.
