Freshwater Shrimp Care at a Glance
Shrimp are sensitive to water chemistry changes — the most common cause of sudden death is improper acclimation or a water parameter swing.

Shrimp Care Setup
Do's and Don'ts
| Drip acclimate ALL new shrimp for at least 1-2 hours — they are extremely sensitive to parameter changes | |
| Provide Java moss, guppy grass, or marimo moss balls for hiding and grazing | |
| Feed specialized shrimp foods or blanched vegetables in small amounts | |
| Use a sponge filter with a fine pre-filter to protect baby shrimp | |
| Keep GH at 6-12 dGH (Neocaridina) for proper molting | |
| Use copper-based medications — copper is lethal to all invertebrates | |
| Add most fish to a shrimp tank — they will eat baby and molting shrimp | |
| Change large amounts of water at once — stability is everything | |
| Overfeed — rotting food spikes ammonia and kills shrimp fast |
💡 The phrase 'they just vanished' usually means they died from improper acclimation and were eaten by tankmates. With proper drip acclimation and stable water, cherry shrimp are remarkably hardy and will breed like crazy.
⚠️ Shrimp are the canary in the coal mine of your aquarium. If your shrimp are dying or disappearing, something is wrong with your water. They are not fragile — they are honest. Listen to what they are telling you.
Freshwater shrimp -- cherry shrimp, crystal shrimp, amano shrimp -- need stable soft, slightly acidic water (pH 6.5-7.5, TDS 100-250 ppm) and zero ammonia or nitrite tolerance. They molt every 3-6 weeks, and a failed molt from copper contamination or sudden parameter swings is the leading cause of overnight die-offs. Feed lightly with blanched vegetables and biofilm.

Why Shrimp Vanish Overnight
Shrimp Tank Setup
The ideal shrimp tank prioritizes stability and safety over appearance. Key elements:
- Sponge filter: Gentle flow; no risk of shrimp being sucked into powerheads or HOB intakes. Sponge also provides biofilm for shrimp to graze.
- Substrate: For Neocaridina (cherry shrimp), plain gravel or inert sand is fine. For Caridina (crystal shrimp), use active soil (Fluval Stratum, ADA Aquasoil) to maintain acidic, soft water.
- Plants and hiding spots: Java moss, java fern, cholla wood, and leaf litter. Biofilm grows on these surfaces — the primary food source for shrimp.
- No copper: Read labels on every additive before using in a shrimp tank. Many fish medications and fertilizers contain copper.
- Tank size: 5–10 gallons is ideal for a shrimp colony. Larger tanks have more stable parameters but fewer shrimp per gallon of visibility.
Feeding Shrimp
Shrimp are detritivores and grazers; they feed constantly on biofilm, algae, and decaying plant matter. In a mature, planted tank with biofilm established, shrimp need very little supplemental food. Overfeeding pollutes the water and causes ammonia spikes that kill shrimp.
- Feed small amounts every 2–3 days: blanched zucchini, spinach, or cucumber; commercial shrimp wafers
- Remove uneaten food after 24 hours to prevent ammonia buildup
- Calcium-rich foods (cuttlebone, kale) support healthy molting
- Avoid protein-heavy foods in excess — shrimp process plant matter more efficiently
