Caring for guppies requires a combination of water quality management, temperature control, feeding techniques, and more. Here are the key points:
1. Water Quality Management
Water Change Frequency and Method
Replace 1/3 of the water weekly; avoid changing all the water at once. New water should be left to sit for 2-3 days beforehand to remove chlorine.
The temperature difference between new and tank water should not exceed 2°C. Pour the new water in slowly to minimize stress on the fish.
Regularly clean sediment from the tank to prevent water quality deterioration.
Filtration and Water Flow
Avoid strong water flow; use low-flow equipment like sponge filters.
Ecological tanks without filters require more frequent water quality monitoring.
2. Temperature and Tank Environment
Water Temperature Control
The ideal water temperature is 24-26°C, with a daily temperature fluctuation of no more than 2°C.
Use a heater to maintain a constant temperature, and a thermostat for assistance during winter or when you’re away.
Tank Setup
The minimum tank size is 10 liters for 6 fish; 20-50 liters is recommended for breeding.
You can add water-stabilizing plants like Vallisneria or Java Moss.
3. Feeding and Health
Food Choices
Feed high-protein foods such as brine shrimp and specialized fish food. Adult fish should be fed 2-3 times a day, while fry need small, frequent meals (5-8 times a day).
Avoid overfeeding to prevent leftover food from polluting the water.
Disease Prevention
New fish should be quarantined separately and acclimated to the tank’s temperature and water conditions before being added.
If abnormalities are found, use methylene blue or a salt bath for disinfection.
4. Handling Special Situations
Short-term absence: Stop feeding, change 1/2 of the water, keep the filter running, and cover the tank to reduce evaporation.
Post-birth care: Isolate the female guppy to prevent her from eating the fry, and provide high-protein food for the fry.
Following these methods can effectively improve the survival rate and health of guppies.
