Quick Acclimation

Quick Acclimation & Setup Tips

Straightforward steps for new arrivals

Quarantine first (about 2 weeks).
New fish should be observed in a separate tank/tub before mixing with other fish. Watch feeding, behavior, and fins. Combine only after they look stable.
Delivery-day checklist (live fish)
  • Have someone receive the box on the first attempt. Don’t leave it outside or in heat/cold.
  • Open in a quiet spot with lights dimmed. Avoid shocks and vibration.
  • Prep: clean bucket/tub, airline tubing (knot/valve), net, water tests. Optional: air stone, heater, aquarium salt.
  • Check for box damage or temperature issues before unbagging.
Important — Breather bags
If fish arrive in a breather bag, do not float or submerge the bag. It blocks gas exchange.
  1. Let the sealed bag rest on a dry surface out of direct light for 10–15 minutes.
  2. Cut the bag and pour fish + bag water into a clean bucket (use a net as needed).
  3. Start drip acclimation from tank to bucket (1–2 drops/sec) for 30–45 minutes. When volume doubles, discard half and continue.
  4. Net fish into the tank. Discard all shipping water.
Skip the temperature-float step below for breather bags.

Before unboxing

  1. Stabilize water: 68–78 °F (20–26 °C), pH 7.0–8.0.
  2. Set up a separate observation tank if possible (2 weeks recommended).
  3. Plan light feeding only for the first 24–48 hours.

Step 1 — Let bags rest (10–15 min)

Open the box, remove the bags, and let them sit out of direct light for 10–15 minutes.

Step 2 — Temperature float (15–20 min)

Float sealed bags in the tank or bucket for 15–20 minutes. Keep lights low. Skip this step for breather bags.

Step 3 — Drip acclimation (30–45 min)

  1. Move bag water + fish into a clean bucket (cut edge; use a net carefully).
  2. Run airline tubing from tank to bucket. Set 1–2 drops/sec using a knot/valve.
  3. When volume doubles, discard half and continue the drip. Total ~30–45 minutes.
  4. Do not add shipping water to the main tank.

Step 4 — Transfer & lights off

  • Use a net only. Discard shipping/bucket water.
  • Lights off for 6–12 hours. Keep handling low.
  • Optional: low salt support (0.1–0.2% = 1–2 g/L) if compatible with plants/inverts/equipment.

First 72 hours

0–24 h Observe. Feed lightly or skip. Keep light low. Ensure aeration.
24–48 h If response is good, feed a small amount (micro pellets/crushed food or frozen baby brine). Test NH3/NO2.
48–72 h Water change 10–20%. Watch for surface gasping, clamped fins, resting on bottom.
Do
  • Match temperature first; acclimate slowly.
  • Be present to receive the package.
  • Confirm NH3/NO2=0 in the first 48 hours.
  • Quarantine/observe for ~2 weeks before mixing.
Don’t
  • Pour shipping water into the main tank.
  • Use strong lighting or heavy feeding on day one.
  • Leave the box outside or in a hot/cold car.
  • Cause rapid parameter swings (big water changes, sudden pH shifts).

Troubleshooting — quick actions

Sign Likely cause Action
Surface gasping Low oxygen / ammonia Add aeration, 20% water change, test NH3/NO2.
Resting on bottom Temperature or transit stress Lower light, keep temperature steady, reduce disturbance.
Clamped fins Water quality / initial stress Small feeding, clean water, observe closely.
Flashing / scratching External irritation or parasites Observe in isolation; if persistent, contact support with photos/video.
Note: The 14-Day Health Guarantee covers rare, health-related losses shortly after arrival. Losses from jumping, predators, disappearance, poor water quality, temperature swings, improper acclimation, aggression, or negligence are not covered. Details: User Guide.
60-second Quick Card
  1. Open box → rest bags 10–15 min.
  2. Float sealed bags 15–20 min. (Skip for breather bags.)
  3. Move to bucket → drip 30–45 min (1–2 drops/sec).
  4. Net fish only; discard shipping water.
  5. Lights off; tiny feeding or skip day one.
  6. Confirm NH3/NO2=0; 10–20% water change within 48 h.
