Fancy Goldfish In A Tropical Tank?

[blue130]

hi everyone, i have a small coldwater tank with 2 fancy goldfish. one i thought had swim bladder but it turns out that he is stunted.
i have a large tropical tank and wanted to know wether i can acclimatize them to that tank?

ive had these guys for 2 years and don't want to part with them but havent got room for another large tank........
any imput please as i don't want them to be at risk or incur anymore unesasery suffering?

I supose they will be alright in there depending on what fish you have, but make sure its not permanent, also see what some of the goldfish experts say.

hi, i definitely wouldn't put them in the tropical tank, as being a coldwater fish they need cool water. are you sure that it doesn't have swim bladder, as a stunted fish doesn't look like it has swim bladder. if i were you, i'd try to find them a new home with someone with a big tank, as fancy goldfish don't do very well in a pond.

cheers

Although most goldfish enthusiasts actually recommend higher temperatures (in the 70s) for fancy goldfish (NOT commons), the general consensus is that they are still unsuitable for a community setup. In addition to the fact that they produce a lot of waste, which would be bad for any nitrate-sensitive tropicals, many other compatability problems present themselves including:

-They will eat any fish that can fit in their mouth (given they can catch it)
-Any fish not small enough to fit in their mouth is liable to bully them as they are terrible swimmers
-There is a good chance they'll devour most of your plants
-Being slow swimmers they can't compete against anything other than other fancies for food
-Their diet is different from that of tropicals and includes a good deal of ash/clay (if you're feeding them good stuff)
-Floating pellets and flakes fed to community fish could encourage them to swallow air while eating, contributing to swim bladder problems
-They stick out like a sore thumb in a tropical tank!

Any chance you could set up a 25-30g for them? Perhaps a hex or cube would be more workable.

This is all good advice, but just to comment on temperature, from a biological and ecological standpoint, the temperature range that goldfish can survive and breed at is one of the largest of most freshwater fish, there is no difference in this capability in any breed (fancy, common etc.) as genetically, they are all the same fish, they are just stable(ish) mutations selectively bred over time. As they orginate from China/Indo-China (which has large temperature variation thanks to its extensive geology), they ca exist at higher/lower temperatures with no ill effect.

But i do agree, goldfish do look really odd in a tropical set up.

They can live in it. Mine do and they're fine.
