Guppies are tough, but shipping and transport are still stressful. Changes in temperature, movement, and confined water can make fish look pale, clamp fins, or hide temporarily. The first week after arrival is about recovery: stable water, calm lighting, and gentle feeding. If you know what “normal recovery” looks like, you’ll avoid panic and avoid making things worse with constant interventions.
What can be normal in the first 24–48 hours
- paler colour than expected
- hiding or reduced activity
- not eating immediately
- clamped fins that gradually relax
What is NOT normal
- gasping at the surface for long periods
- unable to stay upright
- rapid worsening behaviour over hours
- visible spots or heavy mucus
The best recovery routine
- Keep lights low: reduce startle and stress.
- Offer small meals: tiny portions once fish begin exploring.
- Keep maintenance minimal: avoid rescapes and major changes for a week.
- Test water: especially if fish look distressed (ammonia/nitrite must be 0).
Most healthy guppies settle quickly once the environment is calm and stable. The first week is about letting the fish and tank meet each other without constant disruption. When you do that, colour and behaviour usually improve day by day.
