Quarantine new fish before adding them to the main tank. This stops diseases from spreading.
Use a separate tank for at least two weeks. Watch for signs of illness during this time.
- Set up a small tank with proper water conditions
- Feed the fish well and keep water clean
- Check fish daily for any health issues
- Only add fish to the main tank if they are healthy
Regular Health Checks
Check your fish’s health every day. Look for changes in color, behavior, or appetite.
Keep a log to note any problems or unusual behavior. Early detection helps treat issues faster.
- Observe fish swimming and breathing patterns
- Look for wounds, spots, or swelling
- Test water quality weekly
- Remove sick fish quickly to prevent spread
Maintaining Water Quality
Good water quality is key to a healthy aquarium. Clean water helps fish and plants thrive.
Maintaining water quality means keeping it free from toxins and balanced in nutrients.
