They also always remain dormant in the bottom of the tank. These are signs of sick and stressed fish.

Eating Regularly

Healthy fish eat food regularly. It’s a good sign if you see your fish need food daily or after a regular interval. On the other hand, unhealthy and unhappy fish do not eat regularly or spit out food from their mouth.

However, sometimes, fish may not take food for the wrong or unfamiliar taste of the food. So fish lovers should try different foods for their fish. It will bring an outstanding result to your aquarium.
