No, sorry. A goldfish needs at least 20 gallons of water to itself. They produce a large amount of waste and grow to be anywhere from 6-12 inches depending on the kind of goldfish.

6 inches deep is not near deep enough for a goldfish. Would it be possible to enlarge the pooling area? If you could make it closer to the size of a 15 to 20 gallon tank, then you could probably put one or two since the water would be circulating so much...but they do need deeper water than 6 inches. I would say a minimum of 18 inches, preferably deeper...

sorry! maybe I should have said this, I meant those little feeder goldfish, just to be observed in a science lab.

Those little feeder goldfish grow to be about 12 inches long. I have 6 of them now. I brought them home in a small jar, and now they are in a 75 gallon tank and 10-12 inches long. Sorry, the area is still too small. If you want some fish that will stay small, either guppies or platies are interesting but be careful, they will multiply.

really, I never knew that, because there are already goldfish in the terrarium tank should I (I know this is highly unrecommended and frowned upon) put them in my tropical tank?, they really are pretty small still. I read somewhere that goldfish can live in temps from 56 Fahrenheit to 90 fahrenheit.

A tropical tank probably wouldn't work for your goldfish. They are coldwater fish and will get sick if the water is too warm. If your tropical tank is below 75 degrees F, you might be able to keep them there for a month or two, until you can either get a suitable home for them, or give them away. Can you bring them back to the store? Some stores allow trades.

Here are pics of some of my little 10 cent feeder goldfish...

In the first pics, they are in a 2 1/2 gallon tank for pics

The other two are when I was cleaning my pond and took pics to show the shelves -
that is 1 inch inside diameter tubing that they are swimming around...and nice big lily leaves...

the feeder goldfish may be small, but they can grow very quickly. They can reach 6 - 8 inches in their first year easily. Depending on where you are, you may want to try a native minnow. I have mosquito fish in my pond with my goldfish and they stay under 2 inches. They like to stay up on the shelves in my pond, so they may do ok in your pooling area. It would depend on how much of a temperature change you have summer to winter.

Yeah, mine do have more growing to do. My sister has some older fish, also 10 cent feeders, that are more than twice the size of mine. Hers have to go into a 5 gallon to take pics...
