The Oscars fish last as long as you last. It is not something you can keep in the aquarium and expect the same results time and time again. No, these fish should be enjoyed as a delicious meal and then released back into the wild.

While there are lots of variables that could impact how long your fish will live, the main things that affect their survival rate are: environment, water temperature, and diet. So, if you want your finned friends to live a long and happy life, then you need to pay attention to these three factors.

Let’s take a look at each one in detail.


The environment in which your fish live impacts their survival rate. If they are in a clean lake with lots of vegetation and clean water, they will have a much higher chance of living a long and healthy life than if they were kept in an urban tank surrounded by pollution and bad water.

There are lots of factors that impact the environment locally. Vegetation around the tank will absorb harmful radiation, preventing toxins from accumulating in the fish‘s bodies. The water temperature is also key. Warm water supports many kinds of marine life, while cool water is best for keeping tropical fish alive. Finally, the pH levels of the water also influence the survival rate of your finned friends. If you want your fish to flourish, then the pH levels of the tank needs to be around 7.2 – 7.4.

Water Temperature

The water temperature is yet another key factor that impacts the lifespan of your fish. Colder water means fewer animal bodies in your tank, so your fish will live in a rather restricted environment compared to if the water were at room temperature. On the other hand, warmer water means more animal bodies in the tank and a greater variety of food available for your finned friends.

There are certain advantages to keeping the water at room temperature. The main one is that most tropical fish live in tropical waters, where the temperature is more or less constant year-round. So, if you want to keep tropical fish, then keeping the water at room temperature will help ensure that they do not escape!


The diet of your fish is vital for their health and therefore their lifespan. They should eat at least three times their own body weight in food each day to stay healthy. The type of food they eat impacts not only how long they will live, but also the quality of their lives.

Generally, tropical fish favor frozen foods that are rich in nutrition. They also enjoy bloodworms, which they can eat in large quantities. Tropical fish in general do not do well in tanks that are heavily stocked with foods aimed at house pets. They will become overweight, which will make them more susceptible to illness.

One of the best kept secrets of the aquarium hobby is that you can feed your fish a wide variety of foods and give them the nutrition they need without having to concern yourself with weighing or measuring. Your fish will eat what you put in front of them and it is easier to adjust their diet than you would imagine. Simply try new foods every few weeks and monitor how they react to new ingredients.

The bottom line is that your fish will not live as long or as well as you want them to if you do not pay attention to the details. Make sure you offer the right environment by cleaning the tank regularly and feeding them healthy foods. You will also want to keep an eye on their water temperature, since it directly affects how well they will live. For optimal results, water should be between 76-78 degrees Fahrenheit. At this temperature, most tropical fish will be active all day long and enjoy feasting on a variety of foodstuffs.
