Curious What Taking Care Of Goldfish Requires?

Keeping a goldfish healthy really comes down to only a few basic tasks:

  • keep their water clean with a good 50-80% weekly water change
  • feed a good food, ideally in a couple of small servings daily
  • keep an eye on the water quality so you don't have to fix expensive health problems later

Clean Water

Although most people worry more about the size of tank that a goldfish is kept in, those of us that have the most success with goldfish understand that it's more a question of water quality than sheer quantitiy.

A larger aquarium buys you potentially more time between water changes, but how clean you keep the water is the real determining factor as to how healthy your fish will stay.

To that end, these products are the big three keys to success in keeping your fish healthy:

  • clean water
  • an appropriate home
  • healthy food

To that end, these products are the big three keys to success in keeping your fish healthy:

  • a good water conditioner/dechlorinator to remove chlorine from city tap water
  • a test kit to keep ammonia at 0, nitrite at 0, and nitrate between 5-40ppm (more info)
  • a water change system to make maintenance so easy that it doesn't get neglected

An Appropriate Home

While how big an aquarium a goldfish should be housed in is most of what gets people on the internet worked up, the size of the aquarium is really just a proxy for how long you can go between water changes.

We generally recommend most people start with at least a 29 gallon tank for 1 or 2 goldfish, but you won't go wrong with something larger (and it'll be less work for you as well!).

Wondering if you can add another goldfish to your tank?

Forget about "rules of thumb" that still risk your goldfish getting sick, and learn what's REALLY important when choosing an aquarium.

Healthy Food

The final key to keeping goldfish healthy is to make sure they have the vitamins and nutrients to keep them strong and resilient.

Here are the main staple foods we feed around here, so you can be sure your new goldfish will already readily accept them.

The trick to feeding the right amount is to bite the bullet and learn how to weigh your goldfish.

We know, nobody wants to, but feeding about 1.5% of bodyweight daily split into two feedings helps ensure you're not underfeeding (stunting your fish) or overfeeding (bloating them).

If you weight-in every few months not only will you get to see how much your fish has grown, you'll also quickly get a feel for how much to feed without always having to use the scale.

As for vegetables (since everyone always asks), they're not technically required with a good feeding program, but here's our handy guide to what they can add to a diet that might be missing something:
