What is the minimum tank size for telescope goldfish?

What is the minimum tank size for telescope goldfish? My fiance is dead set on a goldfish tank. We want about 4 or five of these goldfish.

How many telescope goldfish can I keep in a 75 gallon tank? I read that each telescope goldfish needs 10 gallon would that mean i can have 7? Also do goldfish require canister filters or can I get by with a HOB, and what GPH should I go for?

 

As for any fancy goldfish, the typical recommendation is 20 gallon + 10 gallon for each additional goldfish, which would land you at 50-60 gallons for the stocking you want.

 

I have three in a 60 gallon and am hesitant about adding another one.

 

It depends on what size and age they are when you get them. You may just want to start with 3 in a 40 gallon.

 

It would more be 1 telescope needs a 30 gallon, general "rule" is 10 gallon per fish after that. However, your main issues of how much of that real estate will you be putting stuff in? Even gravel/sand substrate alone reduces that swimming space! You'll also want to offer 'hiding' places in case one stresses out.

Yes, they're poop factories but they don't like strong flows, so firmly rooted plants will help or back it up with a a sponge filter if needed.

With that said telescopes average 6" - 8" so you can likely get 4 or 5 in there comfortably.
Oh, I went with the fluval 100 gallon canister for my 75g goldfish tank with plants, adding air pump powered sponge filter more so because I like ensuring plenty of oxygen and always want bubbles in my aquariums.

I would like to put a school of panda corys in the same tank, if I did only 4 goldfish how many panda could I have.

You and I think the same way! I have Panda Moors and wanted to add Panda Cory, yes you can do it if your careful and willing to do the extra work:

1) Find the longfin (pricier but get bigger) wild caught variety which are accustom to sub-tropical temperatures which means:
2) A decent heater set at about 22C - 23C (72F - 73.5F)
3) Both Goldfish & Cory are constant foragers so you need to either spread food all around ensuring the catfish eat (sinking / gel foods) or have a spot only the cats can reach and feed them there - you DO NOT want to try to compensate by simply over feeding (Never allow goldfish to eat up top, risk of swallowing air - even soak flakes for a few min and pour in from cup) I add some soaked flakes as a diversion since they will not sink to the bottom right away, the more aggressive eaters will swim about snatching allowing more of the sinking to reach the bottom for the less aggressive
4) As part of above give more areas only your cats have access to hide in case of stress & simple security, smaller caves & more plant cover
5) Ensure your tank is fully cycled/established, it may take you a bit to find those wild caught pandas anyway

Finally, get your Moors first and if your into the Panda thing then may suggest doing same as me. 3 Pandas and 1 Black Moor... just try to get from reputable sources & better quality food to lessen the chances of them all losing their colors! Many places will sell Moors as Pandas but they're not... sometimes a tri-color almost calico even. The rest to your taste of course! That's one of my Pandas as my avatar pic.
So with 4 you can get away with 3 - 6 Panda Cory. They prefer to school, but remember the safe zones... all of your fish will spend all or much of their time at the bottom.

 

5 would be the max.

you can use either a pair of 110 hob filters or a canister or even a couple (2-3) of large sponge filters.

 

You have to take in a lot of factors when stocking a tank. I'd pretty much agree with scorps, but the size the fish grow to depends on a lot of factors. Many fish do not pass 4-6 inches, usually from factors often out of the keepers control, such as early husbandry and genetics. I'd say 5-6 personally. (It is also makes a huge difference where you get them.) It's a bit subjective.

As for the cories, I just don't think it's a great idea keeping fish other than goldfish with goldfish most of the time. If your goldfish do grow to be 6-8 inches those cories could easily become a snack. I've seen goldfish be real bullies to fish half an inch smaller, let alone 4. They may not of course, but is it worth the risk?I

Edit; for an example, I've bought the same type of goldfish from both a small hobbyist breeder and a LFS, the hobbyist fish started out larger, and grew much larger in the same setup a pet store fish didn't grow at all in despite purposely using growth techniques on the LFS fish!!

I'm looking at a 525 gph sunsun canister filter

If I'm thinking of the right sponge filter that sounds pretty good. Ya know what would help filter as well? Live plants!

 

It doesn't matter what goldfish you have- all you need is a 10-20 gallon, or more. You need a filter, air pump, live plants, once a month fertilizer, sand, grass bedding, little hiding spaces, backdrop, and a lid+light. If you didn't know. For fancy goldfish though, and koi goldfish, and a lot of others, will need a 30-40 gal. Common goldfish need 10-20gal. Hope this helped, and if you have any other questions, ask me or anyone else. I know a lot about goldfish. And do know they need colder waters because they are freshwater fish.

I'm afraid you are mixing thing up. 'Fancy' goldfish are the ones with chubby bodies and double tails, and not being as agile as the common ones they need less space and can live in 20 gallons. 'Common' goldfish is closer to the wild type, with an athletic torpedo shaped bodies and single tails, and they need 30 gallons or more, and even bigger for koi, which isn't a goldfish, just a related species of carp. No goldfish should live in 10 gallons long term, it can only serve as a temporary housing for a juvenile.
Also, some essentials you names aren't really essential - air pump isn't necessary if the filter is powerful enough; if by grass bedding you mean carpeting plants, that's nearly impossible to pull off in a goldfish tank (they dig); little hiding spaces isn't really a goldfish thing as far as I know, at least not necessary; background is a choice of aesthetics.

 

But if its 4-5 telescope goldfish- you might want a 40-55 gal.
Okay, I was just giving suggestions if your only gonna have like 2-1 common ones in a tank.

 

Currently I have 4 Moors in a 75 Gallon wide tank, and in a 65 I have 3 Orandas and another Moor. Both have canister filters and a secondary sponge (I like bubbles for that underwater feel so may as well add more filtration + a ready cycled filter I can use if I need to for another tank for quarantine for example).

IMO for 4 or 5 Fancy you should do similar for tank size, and keep in mind your gravel, deco, and whatever else all will subtract from that. Mine are small so planned ahead, and don't have to run out to buy a bigger and bigger aquarium as they grow. Plan for their full size right away.
