Hello,

Do the best that you can for your fish and upgrade when funds permit. Be sure to keep an eye on your water parameters as Goldfish are large waste producers and you may have to do a few extra water changes until you can upgrade. Weekly water changes are a must and again, maybe even more than once per week under these circumstances.

Best wishes for your tank and fish!

Ken

Hi there To be honest, Common Goldfish should not be kept in tanks, they grow too much and they are only suitable for ponds, but now that you have him let's try to do the best for him.

Do you have a filter in your tank? Do not change 100% of the water every time, you are taking all the good bacteria away. If you have a filter you will need to do 25% every week with treated water, not straight from the tap.

I agree with the first part of your post mostly, as common goldfish do get very big and have a huge bioload and either need huge tanks or ponds. Therefore, a 20g won't be sufficient, imo, I'm sorry to say.

The second part I disagree with, as while it's rather inconvenient to do a 100% water change, beneficial bacteria also does not live in the water, rather, it lives in the filter media. So, if you do a huge water change, you don't lose your bacteria, if you change the filter media, you lose all your beneficial bacteria.

I agree that you shouldn't be losing much bacteria in the water during water changes. The main concern with doing large or 100% water changes is if your tap water ph is higher or lower than it previously was in your tank it can shock the fish. Also if doing 100% changes that means you're netting the fish out which is very stressful for them. It's better to do 25-75% changes (depending on your water quality).
