Goldfish With Tropical

[orandas]

Those are not just wild goldfish. Wild goldfish come from Southeast Asia, not South Africa, Brazil, Saudi Arabia, etc. All of these countries have naturalized populations (domestic goldfish that were released or escaped). Granted these are not going to be black moors or ranchus, but they are domestic goldfish that have established wild populations.

All this information is easily found on fishbase.org.

From my own experience I can say that the goldfish I kept in tropical temps did extremely well, in fact they bred repeatedly in my 75 that also housed discus and an achara catfish (amazonian catfish). My fancy goldfish, kept at room temp, did not do this until years after these guys did.

Here is a map I made based on the information available at fishbase.org. The countries in blue are ones that goldfish are native to (like Myanmar and Laos, quite tropical). The ones in red are all the countries that goldfish have established naturalized populations in. As you can see their naturalized range (again, not wild type goldfish, but domestics that were released or escaped) is massive, and includes most of the places all of our other tropical fish come from. Whether or not it is really better for them long term is debatable, but to keep regurgitating the myth that they are coldwater fish is simply inaccurate.

whoo......how big is ure tank? and how many goldfish do you have? Hope u have more than 1 female goldfish.

look at that poor dicuss cowering under the ornament, under that breeding frenzy.....wow wud not want to be under that rugby scrump.

Well far be it for me to add oil to the flames but.... When our goldies were in the big tank with the heater on to keep the filter going they were sh...machines, that was at 20deg or so.

Now in my daughters tank at a cool 15 there is not nearly so much poop, you have to look for it to suck it out. I would say he's more alert too.

i think i will just have tropical fish in my tank nut thanks for helping

I had this same conversation with fishguy2727 before on another thread.

In his words:

"For the record fancy varieties cannot tolerate the same temp range that long-bodieds can. The fancier they are the more sensitive they are. They cannot go as cool or as warm as more natural varieties."

This is why I personally wouldn't have them (fancy varieties) indoors unless it's in a cool basement. From what I've personally seen, they will not do as well and are prone to illness and disease at even ambient room temperatures of 18C or higher consistently. I don't need a scientific paper to tell me this, I have seen it firsthand.

I recall a similar thread only a few months ago, there's no scientific evidence that cites that keeping Goldfish at tropical temperatures is detrimental to their health (Unless you go over 28/29oC as certain enzymes are denatured and stop working).

The fact of the matter is that Goldfish are more or less incompatible with most tropical species anyway, not because of water temperature, but because they'll eat or be eaten.

Standby has it spot on, Goldfish are indeed eurythermal (like a few other hardy fish), and not only that but their 'breeding' curve spans a much larger area than most aquarium encountered species. There is some truth to the idea that the more intensive/selective bred species (particulalry celestials/lion heads etc.) have more trouble coping with lower/higher temperatures than most goldfish - due to innumerable reasons, but generally that breeding has made them poor fish). Provided a gold fish is acclimated, there is absolutely no reason they would not do well at higher temperatures.

However, as Stantby kindly mentions, their compatability with generally enountered tropical fish is somewhat limited, their feeding habits, rooting activities, boistrousnous etc. are not always a good idea for a peaceful community, also, at higher temperatures goldfish are able to process feed much faster, and indded do become 'poop machines' and so need very good filtration...

It would be nice if the myth that goldfish can't/shouldn't be kept at higher temperatures were to be completely dispelled (this will probably never happen - just like 'fish growing to the size of the tank', or 'internal organs bursting' due to cramped conditions etc.), the message should instead be: its inadviseable to mix goldfish with tropical community fish without much forethought and planning.

 

[fishguy2727]

My point with that quote was that the fancy goldfish cannot go AS warm as long-bodieds. It really comes down to what temp you are going to keep them at (as well as what fish they will be with and if there is even a reason to keep them warmer than room temp).

Long story short: It isn't advised. SBS's point it probably the most important - will they be eaten by their tankmates or will they eat them? If kept in the proper size tank, goldfish can get far larger than most people think:

 

[fishguy2727]

They do get huge, if they morph in to koi.

They do get huge, if they morph in to koi.

lol; I was just going to mention that.

They do that if you keep them too hot you know

 

[eaglesaquarium]

They do get huge, if they morph in to koi.

I know, but the picture was too cool not to include it in the discussion. This fish only got so big because it was kept in such a big tank...a natural waterway.

Guys while a good debate is healthy a reminder to show respect when answering posts is very much the way of this forum

 

[tropicalfish311]

ok well can i feed then tropical flakes

would it be ok if i kept them at 78 degrees

 

[fishguy2727]

Details:
What size tank?
What type of tropical fish?
What type of goldfish?

I only feed and recommend New Life Spectrum. It is by far the best fish food out there right now and would be ideal for both the goldfish and any tropical fish.

Slightly hijacking the thread with a question, I've became quite keen on Goldfish and wouldn't mind keeping a few oranda's. Theres so much conflicting advice on-line so what would be an ideal tank size for 3-4 that would allow them a healthy growth??
