I've seen more than a few goldfish threads pop up recently. Knowing that there are a few goldfish fanciers out there, I thought I would create a place where we can all share pictures and chat about anything goldfish. Goldfish ponds. Goldfish art. Even the mistreatment of goldfish (we all know the feeder tanks are horrible so try to keep this to stories about how their condition was improved). There is a lot of sadness surrounding goldfish, but let's keep this positive. Feel free to ask any quick goldfish questions here and we'll do our best to answer them!
BASIC GOLDFISH CARE
- Stocking rules of thumb for fancies: 20 gal for the first fish plus an additional 10 for each other fish
- Commons really get too large for normal aquariums and are best kept in large outdoor ponds. The can be temporarily housed in 55 gal or larger tanks. Most places suggest a 100+ gal tank if you want to keep them inside permanently.
- tankmates: goldfish are social fish and prefer company of other goldfish; two or more is always better; lone goldfish may be shy
- temperature: Due to the deformed nature of the digestive tract of fancy goldfish, they can't digest food well below 70F, heating the tank to the mid to lower 70's even in the winter will help keep them from becoming constipated and bloated
- plants (this is a tricky one): some people can make this work and others can't; it depends on your fish. Plants that have had success in the past: hornwort, anubias, java fern, large amazon swords, anarcharis, ludwigia. I've also found it helps to introduce them to plants when they are young.
- filters: goldfish poop a lot and need strong filters; at least double filtration is recommended when using HOB's
- stocking: no hard rules here just remember that less fish means less waste and that goldfish are known for reproducing in ponds
- temp: stop feeding goldfish when water gets down to 60F
- plants: marginal plants best, floating plants good to provide shade
- filter/water movement: essential to getting through the winter, keep these going year-round to prevent fish kills
- Do goldfish really get that big?
: Yes... Yes they do. Photo proof:
- How long do goldfish live?
: Average for a propyl cared for tank goldie is 10-15 years. Average for a properly cared for pond goldie is 15-20 years.
- What do goldfish eat?
: Goldfish are omnivores which means they can and should eat both plant matter and animal matter. Younger goldfish need a higher percentage of protein (30-40%), but older goldfish should only get 10-20% protein. For a tank fish you can provide a complete diet with a high quality pellet food supplemented with fresh greens or with a gel-food diet (my preference as it goes a long way to prevent floaty issues in fancies). For pond fish, a high quality pellet diet will do as goldfish will get their greens from the pond plants and algae.
Normally I would start off by sharing my fancy goldfish tank, but it's undergoing a major revision right now. I'll have some pictures of that for you in a week when it is all done. I promise they will be worth the wait.
Instead I'll show you some pictures of a little goldfish pond I found while visiting family in Ohio.
This is the pond. Mostly crowded with lilies but near the skimmer it was clear so I could get some pictures of the lovely little goldies!
I lured them out of the lilies with food. But it was getting to the point where they shouldn't be fed anymore, so they were a little slow.
