Environmental Stressors
Molly fish can show signs of stress or poor health due to their environment. Stress weakens their immune system and causes illness.

- Avoid mixing too many different fish species together
- Watch for signs of aggression or hiding due to crowding
- Keep plants and decorations to give fish places to rest
Temperature Fluctuations
Mollies need stable water temperatures to stay healthy. Sudden changes stress their bodies.
Temperature swings can weaken immune systems and cause disease.
- Keep tank temperature between 72°F and 78°F (22°C – 26°C)
- Use a reliable heater with a thermostat for steady heat
- Place tank away from windows or vents to avoid drafts
- Check temperature daily with a thermometer
