Gold fish From Tanks To Outdoor Ponds

I have 2 tanks each with 2 goldfish.

All the goldfish have grown to a size where the tanks are not big enough......we do not have the space to buy bigger tanks.

Is it possible to put them in a pond outside or would this mean certain death (which obviously is something I want to avoid)?
Many thanks

Hi

If your Goldfish have outgrown their aquarium, you must be giving them exceptional care...well done!

Many Goldfish keepers have heard the myth that Goldfish grow to the size of their container. This simply isn't true.

Moving Goldfish outside periodically is something I recommend as the sunlight seems to give their health and color a boost.

Before moving fish outside there are a few points to consider:

Time of year. The best time is during the warmer months. Goldfish kept indoors are usually at a higher average water temperature than outside, so don't hibernate or at least slow down during winter.

If you put fish out during winter, it will be a shock to their system to go from active to hibernation mode overnight. They won't have built up any fat to take them through the winter months so come spring they will be in poor condition and many fish die at this time of year.

You didn't mention if you have a pond already, so I am assuming you haven't.

Read my pages on Goldfish Ponds if you are planning on getting one. Like real-estate, location is everything!

One last point, you didn't mention what variety of Goldfish you have.

If they are a single tail variety, they will thrive in a pond. Some of the fancier varieties aren't as hardy and if you live in an area that experiences severe winter temperatures, consider bringing the fish indoors during the coldest months.

My Fish Keeps Growing
by: Grant

I wish all my queries were like yours. You have managed to keep a Goldfish healthy for a decade, so you are obviously doing something right.
I wouldn't release him into the pond because of natural enemies that would love his bright colors. He isn't accustomed to avoiding whatever wildlife you have in the vicinity.
Consider selling him to either a local pet shop, or on the Internet using something like ebay, or social media like Facebook.

My fish keeps growing
by: Goldfish mom

I am struggling with deciding on what to do with my goldfish. He is almost 10 years old and I have a medium sized tank mainly because I don’t have space for a larger one and health reasons I just can’t clesn a big tank. We have a large pond on our property and hubby keeps saying I should let him loose. I almost feel like what if he dies right away but then I feel bad because he’s outlasted the fish that we put in with him years ago and now he’s just too big to add more fish to the tank. I don’t put any chemicals at all in his water his tank is straight well water from the sink. I honestly am shocked he’s lasted this long.

Follow Up to Transferring From Distilled Water to Outdoor Pond
by: Anonymous

Thank you for your response. Just to clarify, our goldfish has lived in entirely distilled water for about 6 years. I had no idea about the salt issue, so thanks for your information on that.

This is the bottom line... We realized that our goldfish was stressing out, not due to our adding small amounts of pond water to his tank, but because we had turned his filter off! We think that he was not getting enough oxygen. Once the filter was turned on he (Jepetto) got his voracious appetite back and resumed his spunky, little personality. It's May now. We are hoping to release him into the pond possibly in June, where he will join hundreds of other goldfish and be given the opportunity to eat live food in addition to goldfish food, and possibly find a girlfriend. Thank you for sharing your knowledge. We really appreciate it.

Distilled Water Tank to Outdoor Pond
by: Grant

Hi

When you describe the water your Goldfish is in as distilled, therefore having no chemical elements in it whatsoever, I'm a little surprised. Goldfish can't live in distilled water because the salts in their bodies would leach out.
This is why adding some un-iodized salt to their water when they are sick helps them recover faster because it brings the water salinity closer to their internal salinity.
To answer your question, I suspect the water chemical makeup is very different from the outdoor pond water. Your fish is exhibiting symptoms of pH shock.
First, test your water pH (should be 7.0-7.6), nitrate levels (below 50ppm) and ammonia levels (it should be zero). One result will be very different from the other. After correcting the water conditions that are poor, the fish can be acclimatized to new water conditions by adding a little to its tank over several hours.

From Distilled Water Tank to Outdoor Pond
by: Anonymous

We obtained our goldfish about 6 years ago, as a result of it being the only goldfish that survived being subjected to numerous chemicals in a science class. It has lived in distilled water ever since and has thrived. We would like to transfer the goldfish to an existing pond that has many goldfish living in it. The problem is that when I include a small amount of pond water into his tank, his appetite diminishes and he mouth exhibits gaping behavior. Is it possible to transfer this fella or are we going to kill him by doing so?
