Goldfish In Tropical Tank?

[Ch4rlie]

Hi,
 
Whilst I was at work today, I came across this 3f x 1f x 1.5f tank with decent filtration system and heater.
 
This tank I would guess is around 130 Litres or 34 US Gal, that tank was holding a Yellow Goldfish, a Speckled Goldfish and 6 Bristlenoses!! 
 
I was fascinated by this and never knew goldfish could be kept with tropical fish.
 
Is that ok to do? Goldfish with tropical fish? Obviously can't have any fish too small compared to goldish otherwise is dinner to goldy!!
 
Have other people come across this or actually do this for their own tanks?
 
Just a fascinating new way of looking at tropical fishkeeping for me! Not that am really tempted to do this, just useful knowledge in case anyone ever asks.

It's not a good idea because goldfish prefer the cooler temperatures. So they will survive in warm water but wouldn't be as happy as they could be in a cooler tank or a pond.

When I was younger my mother had a black moor that got huge but he wasn't a very hardy fish so he was in the pond most of the time but then when it got cold during winter my mother would keep him in the tropical tank for a while, and then back in the pond for summer! Like I said I was younger so I can't remember if he was a happy goldfish in the tropical tank but I know when he got really old my mum bought a small tank (no heater) to keep him in on his own because he wasn't tough enough for the pond anymore.

Yes, that is what I presumed as well, but having done a little research I have found that Goldfish actually do better in warmer water, they can endure cold temperature as well as extreme warm waters up to 90F!
 
So they can easily live in tropical water parameters! 
 
Apparently!

Goldfish in Tropical waters is a bad idea as it speeds up their metabolism and with Goldfish technically not having a stomach this means more often feedings and they grow quicker, bigger and poop more if in tropical temperatures. Hence why it is a bad idea.

Hmm, interesting..........
 
The yellow goldfish is about 6 to 7 inches long, the speckled goldfish about 4 inches long and looks like they have been in that tank awhile and swimming around ok. 
 
The BN's are only about 3 to 4 inches but 6 of them in that tank with these two goldies!!
 
Just fascinating but probably not the best idea but having said that this tank is in a sort of science materials research lab (just to let you know, nothing to do with animal testing or anything like that at all) with clever boffins working there so maybe they know what they're doing?
 
I hope.......

Nope if the Goldies are in a tropical tank Goldies are comfortable up to about 22c as far as I'm aware which is the very low scale end of Tropical/high end of sub-tropical... Any higher and their metabolism increases, they poo more and they grow faster and bigger. The tank isn't big enough for the Goldies let alone the BN's too. I'm guessing the "speckled goldy" is a shubunkin which, along with the lemon goldfish, need a 200l tank plus 45l per extra one bare minimum. So those two need a 245l bare minimum but a pond would be better.

 

[Ch4rlie]

Wow!
 
I sure have learned from this and certainly won't recommend to anyone who is even considering having goldfish in a tropical set up.
 
That's a shame then really.
 
Poor little fishies! (ok, maybe not so little!)

 

[Paradise3]

Yeah, it's a shame really..

I have 2 fancy goldfish, 1 oranda, 1 black moor (although he turned completely orange so I guess he's just a telescopic eyed goldfish) and I was wondering how well they would do in the pond outside, it has golfish (some quite large) comets and shubunkin types. Would it be cruel to put fancies outside with other faster swimming goldfish (my fancies are about 2.5'' in size - not including the tails)? I have had them over a year and don't appear to have grown, maybe they could go in the pond when they get big, in a few years?

fancies shouldn't be kept with comet's/commons or Shubunkins as they can out compete them for food and bully them with the fancies being slower so they would need a different pond or to be kept inside in a big tank unfortunately.

not good, goldfish are cold water fish and should not be in tropical waters. they can survive in it, but with the bio-load it can harm the other fish.
