You know your guppies are happy if they exhibit signs of being happy and healthy including:
- Smooth and brightly colored scales with no discoloration
- No bumps or abnormal growths on the body
- Flared out fins
- Clear, normal eyes with no clouding or bulging
- Normal breathing, not too slow or too rapid
- Active swimming
- Healthy appetite
- No hiding
Fulfill your guppies’ basic needs to keep them happy. Give them ample swimming space and avoid overcrowding their tank. Monitor and maintain the tank’s water conditions regularly. Feed them a healthy diet of high-quality flakes and freeze-dried grubs. Lastly, keep them away from aggressive tankmates.
