Why do fish die when they eat too much?

Impact on Water Quality If the fish aren’t able to eat all the food you give them, the leftover food in the tank starts to rot. These compounds are toxic to fish and can even be lethal at high levels. In addition, uneaten food that is left to rot in the tank can lower oxygen and pH levels.

Will fish stop eating when they are full?

Why is my fish leaving food in the tank?

When they are fed in this way, they will eat their fill and leave over the rest. This will not only lead to large amounts of food waste in the tank, but will also mean that fish are left malnourished in between feedings. Ideally then, schedules which include multiple small feedings will keep your fish healthy.
