Two would be best in that tank and no more!! It just isn't enough room for three goldfish because they are messy and produce a lot of waste. If you just have one or two you will have healthier and happier goldfish which will stay with you for a long time Smiley

Welcome Honey to the forum.

As Andrea said, you will have much happier and healthier fish if you stick with 2 goldfish. General rule is 10 gallons min per goldfish.
They eat a lot, nibble the whole day on aquarium plants, they produce lots of waste. Therefore it is very important too keep the water quality right. It is more difficult with a small tank and too many fish in there than with a bigger tank and less fish.

Do you have the appropriate test kits? You will also need water conditioner, pH-UP and pH-Down powder, Pimafix, Melafix, to have a basic "Care Kit" for your fish. And different food such as flakes, crisps, pellets, variety of frozen food like brine shrimp or bloodworms.

Any questions? just ask, we are happy to help  Wink

The actual, and absolute minimum amount of water that an adult goldfish needs is 20 gallons. Then you add 10 gallons for each goldfish. So you could try to get yourself a 35-40 gallon, and you might have a better chance at fitting 3 fantails there Smiley They are still a bit smaller variety of goldfish, so a 30-35 gallon should be alright for them Smiley AS LONG AS YOU HAVE GOOD FILTRATION AND AERATION IN YOUR TANK. This is incredibly important when keeping goldfish since they are messy, and they need as much oxygen as they can get, especially during hot days.

That sounds good Smiley So you already have the fish?

Either way, it's a bit better if you'll change smaller amounts of water and instead doing it weekly, so about a third of the water every week, this will help keeping track of your nitrate levels Smiley By the way, do you have any tests for nitrite and nitrate? These two will start appearing as soon as the ammonia is gone, and around then, it should be safe to add the new fish Smiley Post photos!!

I do recommend the API MasterTestKit: it has solutions to test Ammonia, Nitrite, Nitrate and pH. Best value, much better than buying the single tests....

Yep post photos please, happy you go for 2 fish. Later on you may upgrade to a bigger tank and be able to keep few more  Wink

creamkiller: No, don't say three. No matter how good the filter is, there WILL be problems with the water quality after a while when the fish are growing. It can't be avoided when you have an overcrowded tank, simply. You'll end up having problems not only with that, but you'll have stressed and sick fish + extra work for yourself when you'll have to change the water more often. It will be more expensive that way than doing the simple investment in a tank as big as possible from the start while keeping less fish in it.

Creamkiller
you must not get angry or upset, absolutely NO REASON for this  Wink
Just respect everybody's opinion. Using a super filter helps a lot, of course, I agree with that ... but it doesn't give the fishies enough space to swim... this is my view of things....

creamkiller: I know that a bigger filter helps the fish ENDURE living in a crowded tank, but you need to remember that this should be a temporary solution only, don't go telling people who have the possibility to avoid crowding the tank that it's perfectly fine to do so d: If you catch my drift d:
It's like Hanna said earlier, a fish also needs space to swim, and a crowded tank will stunt their growth. They NEED a certain amount of space to be able to thrive in captivity, right? Smiley

Don't worry about your karma d: I ain't gonna touch it d:

Hi Creamkiller,
Sure. We all are here on this forum to discuss about our fish and what's involved with fish keeping. I'm straight forward too, lol  Wink

But you ARE wrong. A super, super good filtration keeps the water good for a certain period of time. But it doesn't make the tank bigger to give them plenty of room to swim and enjoy themselves. The tank is still overstocked.

This are two different things now we are debating:
1. filter capacity

2. tank size + overstocking

but if u have alot of decor in your tank rocks included it could make your 30 into a 25 so if u have a 25 and have less decor in it it could be the  same amount of water to swim in.


plus a longer tank is better then a tank that is higher so if the 25 is longer then the 30 the fish will have more room to swim( fish swim mostly east west not north south)

i have seen a tank that is 1.5 feet high but is 300 gallons the fish love it i have seen a 3 feet high 300 gallon tank but they dont like it as much less room to swim back and forth what do u think

One more thing that's important about long/high tanks, is that the long one has bigger surface area, and this is incredibly important for the fish! So something with bigger surface area, will easily be able to support more fish since the space for gas exchange is larger. And, I wouldn't squeeze any fish into those high tanks d: They do look awesome, but I don't find it very comfortable for the fish. Even if it's the same size as a long tank, it seems less spacious.

And of course, the decor takes up lots of space in a tank! Especially big rocks and the like Smiley So that's why, I THINK, a bigger tank is better since it seems that less space is lost on decor. If you know what I mean Wink

YES, ALL IS TRUE ! Wink

Also in high tanks fish don't feel comfy because of the increased water pressure.

Hello,
I have few things to say about all this!
1)  I'm gonna miss ya Cream Killer now that you don't have any more goldfish.  You make me laugh!  Grin
2) What Cream Killer is saying is right, about having enough or extra filtration in an overcrowded tank.
3)  ALL my tanks are overcrowded!!!  Heck I have 10 pond fish in a 75 g tank!
4)  For the new person just getting started I DO NOT reccommend overstocking so for YOU NEW PERSON reading this please use the calculation of 1 goldfish per 10 gallons of water.  Otherwise you will get discouraged, and stressed with water quality issues and unhealthy fish and give up on this wonderful hobby!
(Yikes! there goes my karma LOL) Wink

All interesting comments.

In my opinion, I like to use this calculation -  2 gallons per inch of goldfish (not including tails).  If you have one 10-14" goldfish, I don't think he'd be comfortable in a 10 gallon tank.  He may not even reach his full size potential in a 10 gallon tank.

But you wouldn't want to keep a 1 inch goldfish in a 2 gallon tank either! Smiley
That would not only be sheer cruelty but your goldfish would pollute that tank very quickly just by breathing.
Goldfish are extremely messy and use up alot of oxygen and excrete ammonia through their gills just by "breathing".
Not to mention they need room to swim and grow. Wink

I agree.  I think the minimum should be 10 gallons for a juvenile fish.

I meant that one should try to calculate tank size based on the full-grown size of their fish, or plan on upgrading as your fish grow, always leaving some room for the fish to grow into.

I agree with Summertime Smiley I find it better if the fish grow bigger, to calculate the needed amount of water along with their length! Because it's like she said, a 14 inch fish wouldn't be comfortable in a 10 gallon setup.

Well, I agree with that too but if someone has a 1 inch fish you DO NOT want to buy it a 2 gallon container.
I just wanted to make it clear.
If all you can afford is a 10 gallon tank right now then just get 1 or 2 at the most goldfish and plan to upgrade in the near future.
I REALLY WOULD ONLY RECOMMEND FOR SOMEONE GETTING A 10 GALLON TANK 1 GOLDFISH! Grin
but....PEOPLE OVER BUY, OVERSTOCK AND UNDERCALCULATE ALL THE TIME!  I guess it's just human nature.... Cheesy
It's like lets see how many goldfish we can cram into this tank! Wink
When it comes to goldfish keeping less is more! Smiley
