✦ both Fred and George-– Keith and Mary Allies won this set of goldfish at a reasonable price in 1974, when the couple were just dating. They are currently married and their set of fish last matured at 40 years in 2015. It has not been identified if the fish are still alive.

✦ Hey- Sharky, 24 years old in 2012, was a white goldfish won by Paul Palmer at a neighborhood party when he was 4 years old.

Sharky had a near death experience when he was discovered face up in his plate and also flushed down the bathroom. Still active, he swam right back up.

Average lifespan by species

Aquarium owners are constantly asking how long their fish can live. The truth is that there is no personal solution to this question - it varies depending on different aspects. Normally, small fish have a shorter lifespan than large fish, and fish that lay eggs tend to live longer than viviparous fish.

Two of one of the most prominent types of aquarium fish are at opposite ends of the age range. Betta fish live an average of 2 years, while goldfish can live for years. Any species of fish can live longer than its expected lifespan, but with quality care and a healthy and balanced diet.

Some of the fish with the shortest life expectancy are killifish that only live for a year or two. Bettas come next at 2 to 3 years, although some have gone on to be 5 years or even longer. Viviparous fish such as platys, mollies, and swordtails generally live less than 5 years at best. Other species in a smaller area, such as tetras, rasboras, and so on, go online around 3 to 5 years.

The tropical species that often live the longest are fish, loaches, silver dollars and certain types of cichlids. Things to remember with goldfish is that the majority of them are not cared for properly. There is a typical mistaken belief that fish will just grow as big as their container will allow, which is simply not true. A large area, high water quality and a nutritious diet are essential for any type of fish to achieve a long life expectancy.

Here are some additional tips:

Give your fish more space than it needs. There is a general rule that your aquarium should be one gallon in size for every inch of fully grown fish. You can use this as a starting point, but it never hurts to bring a few extra gallons.

Lower the fear as much as possible. You may not think so, but fish can become stressed due to environmental changes or hostile tank mates. If you keep several males, make sure the tank is big enough to fit a number of areas with enough design to separate lines of sight so your fish don't get jittery.

Use proper tank equipment. Filling a tank with water is not nearly enough to keep your fish healthy. You need a three-stage purification system to remove strong and also dissolved wastes from the water and also a boiler heater to keep the right temperature in the storage tank.

Evaluate your water once a week. Points change quickly in a confined environment like your tank, so test the water once a week to make sure everything from pH to salinity is within the correct range depending on the species you're maintaining.

Buy high-quality food. Figure out what kind of diet your fish need in the wild, then approach it as carefully as possible with both commercial and fresh foods. Supplement an herbivore's diet with fresh vegetables and an omnivore's or carnivore's diet with things like saltwater shrimp, mealworms, and forage fish.

Add some real time plants to your container. Despite not breathing air, fish still need oxygen and adding live plants to your tank can help with CO2 exchange. The better the water quality in your aquarium, the healthier your fish will be.

Make regular water adjustments. As your fish eats and lives, it generates waste that breaks down and adds dangerous chemicals to the water. Performing weekly water changes will refresh the water and keep the environment safe and healthy for your fish.

Although tropical animals are much different from traditional animals such as canines and domestic cats, they deserve no less quality treatment. Take what you've discovered below to provide your tropical fish with the most effective care possible to maximize their life expectancy.
