Goldfish Care: How to take care of goldfish

Goldfish care - never keep goldfish in a bowlFirstly, well done for taking the time to research proper goldfish care!

Jump straight to a particular goldfish care article using these links or browse all of our goldfish care articles here.


Unfortunately, many people don’t bother to find out about proper goldfish care, and think that goldfish can simply be kept in small, unfiltered bowls. Often, this isn’t the fault of the person caring for the goldfish, but the fault of pet shop staff.

The sad fact is that there are far too many pet shops still selling small bowls (some places have banned this, but unfortunately it’s still legal in many countries) and far too many ill-informed people working in pet shops (particularly large chain stores) that give very bad advice to inexperienced goldfish keepers. This inevitably leads to poor goldfish care, goldfish living very short lives and some very unhappy fishkeepers.

So, whether this is your first experience of keeping goldfish, or whether you’ve made some of these common mistakes in the past: well done for putting the effort in to get it right this time!

By finding this guide to proper goldfish care and reading the articles below, you’ve given your goldfish a much better chance of living a long, health and happy life!

  • totally newbie

    For the size of the tank, is it still 10gallons for every gold fish? Even if they are just feeder fishes? Thanks for your advice.

    • TheGoldfishTank

      Hi there.

      Yes, we’d say 10 gallons absolute minimum for any goldfish.

      There’s really no such thing as “feeder fish” – they’re all goldfish, all goldfish have the potential to grow to a foot long or more, and they therefore need plenty of room to grow.

      Hope that helps!

    We got our goldfish 10 months ago at a County Fair for .10 ring toss. Brought him home 30 miles in my GF’s lap on my motorcycle. He’s doing great, getting bigger all the time and this website has really opened my eyes up. We did get a 3 gallon tank w/ filter and air pump after we had him for 2-3 months. got him out of the fish bowl! Thanks for the info..
