Gaining Knowledge on Fancy Goldfish
 
I have always wanted to own Fancy Goldfish, but am afraid I couldn't maintain the properly. I have several question....so here we go:

1. Knowing that goldfish prefer cold water, can they also adapt to temperatures in the mid 80's? I live in Chicago and
like to have the windows open on some hot summer days.

2. As I said before, I have a 27gal cube tank and was wondering I'd I could fit 2 Fancy Goldfish in my tank. I
remember hearing one time that the first fish needs 20 gallons then every additional fish needs 10 gallons, is this
true?

3. I have a Marineland Penguin Bio Wheel 350 which creates a somewhat fast current, can the be a problem? I also
have a 5" round air-stone.

These are just question that I always wanted answered, and as a fairly new member to this forum I thought it would be a great place to post. As I said before, I am not currently looking to buy these fish, but am hoping to one day.

Thanks,

In answer to your third question, it's a good idea to have air and oxygen cycling throughout the tank, but don't create too many currents. This can stop your fish getting into particular areas as they will be pushed away, and this can stress them. I have a filter which brings the water out of the tank and flows it back in at another point. It has a small current, and my fish are okay with that.

And don't put in too many bubblers and air stones, your fish may get caught in the bubbles and be pushed away, which can also stress them out.

Good luck with your Fancy Goldfish!

About the temps - I read somewhere that most of the goldfish you can buy at the stores (not the ones you can import from Hawaii or Japan) have been raised in tanks with heaters and can acually take higher temperatures. I'm not sure about mid 80s as that is high for most tropical fish in general. I keep mine in tanks around 75

Also, most fancy goldens are smaller than the common/commets so in my opinon 27 would be fine for two but no more. Depending on what type most fancy goldens get to be about 6-8 inches full grown, but just because they are small doesn't mean you can stuff more into your tank.

The other thing to consider is decor and substrate. If you are getting fish with bubble eyes or long fins then make sure you have no sharp corners on your decor. As for substrate - I prefer a bare bottom tank. Its not the prettiest, but it is so easy to keep clean. Some people say goldfish choke on gravel, or eat sand, but I have no experience with either. If you don't like barebottom, then I would suggest large smoth river rock or large polished stones.

As for plants. I gave up. They became salads for my goldies. I didn't even try with plastic plants... but I did always have a few pothos clippings tucked into the back, I've even had spiderplant clippings. but again that is up to you.

I hope I haven't discouraged you as Goldies are my favorite fish by far.

Thanks for the great information! I was hoping to get a black sand bottom too really make the colors pop along with a piece a driftwood in the corner and ad you said some larger flat rocks. Do you have any bottom feeders along with your goldfish?

I kept Otocinclus with them - but keep in mind that after a few years they might become snacks. My goldfish never bothered them though. Oto cats can be sensitive at first, but once aclimated they are great. I love them as they eat the brown diatom stuff no other fish will.

I personally do not like plecos - so I don't keep them.

I have heard that chinese algae eaters will suck the slime coat off fancy goldfish because they are slow movers, so I'd skip those as well.

I have also kept snails in my tanks, once they are large enough there isn't a problem, and if the snails breed, the goldfish have snacks so you don't have to worry about population control I had a large Ramshorn snail and quite a few mystery snails without any issues.

I'm sure there are others but one thing to keep in mind is the bio load - goldfish are dirty but so are many bottom feeders. So unless there is a reason you need a bottom feeder - personally - I'd skip it, especially since you are already close to the max with the two fish. Although at first when they are small it wont seem like it, and you will be very tempted to fill the tank.... resist the urge!!! LOL...

And I would suggest keeping two fish because goldfish are very social fish and they need someone to keep them company. I have had them solo, but they just seem happier with two or more.


Oh - and I think the black sand and driftwood with rocks would be just great. If the wood is too pointy, you can always sand a little down.
