A fish aquariums water should be changed every 2 to 4 weeks or at least once per month.

You can do a half water change as well and not remove the fish.

You should do a 25% water change every two to four weeks.

There is no reason to remove the fish during the water change.

Make sure you stir the gravel or use a gravel cleaner during the water change.

A pet goldfish should be fed between 2 to 3 times per day.

Adult Goldfish can sometimes be fed only once or twice per day.

Pet Goldfish live between 10 to 15 years when taken care of properly.

The average lifespan of a pet goldfish is 10 years although some pet goldfish may live as long as 15 years.

I had a pet goldfish that lived to 16 years but that is rare and then I had another pet goldfish that only lived to 5 years old.

Goldfish can live for long periods of time if they are fed a varied diet and housed in proper water conditions.

The average lifetime of a goldfish is ten to fifteen years.

Surprisingly the longest lived goldfish on record lived to age 43.

The misconception that Goldfish don’t live long is as common as the misconception that they have short memories.

These fish are members of the Carp family Cyprinidae, which are known for their long lifespans both in the wild and in captivity.

Their close cousin the Common Carp can live up to 20 years.

Goldfish are a domesticated variant of wild Carp and they will live longer if they are housed in an outdoor pond setup that closely mimics their natural habitat.

If you are keeping them indoors, their tank should be at least 50 gallons.

Common Goldfish

Wild Carp can live up to 10 years, but are more likely to live for 4 or 5 due to the risks of predation, disease and competition with other fish.

In captivity, they can live for 10-14 years in a tank that is at least 50 gallons.

Proper tank conditions, room to grow and a healthy and balanced diet make all the difference.
