You want to make sure that the water does not freeze all the way. Fish usually go into a dormant faze were they appear to be dead. They army to hardy so don't be surprised if they don't make it. I've had one that's survived 2 years.

Can you put a goldfish in a one and a half gallon bowl?

If it is a small goldfish, it will physically fit in something that small. But, it will not live very long in it. If you wish to keep goldfish alive, you need at least ten gallons of water for each goldfish along with a good filter and a heater to keep the water temperature stable. With proper care goldfish can easily live 15+ years.


How often do you have to clean out a goldfish without a filter?

Every Second! Gold Fish are Very messy and need a filter to keep them alive. I suggest you put your Goldfish in a pond. Make sure there is more than one, Goldfish have friends just like you and me. Or you could get a 20 gallon tank (the tank has to be big enough so goldfish can grow up to 10 inches long WITH a filter. okay long story short, one inch per fish needs at least a gallon!

How many bubble eye goldfish can you have in a 1 gallon tank?

ZERO!! A 1 gallon tank is not large enough to keep any kind of fish in. A Bubble eye goldfish can grow to 10 inches long and so, using the basic rule for keeping fish. "1 inch of fish need a minimum of 1 gallon of water" you would need at least a 12 gallon tank to house 1 Bubble eyed goldfish.


What is better putting 20 goldfish into a ten gallon tank or buying ten 1 gallon fish bowls and putting two fish in each?

Neither! A goldfish needs at LEAST 20 gallons of space, adding 10 gallons for each additional goldfish. For example, I own 2 fantail goldfish, and they live happily in a 30 gallon tank. The reason goldfish die so quickly is because people put them in such small containers, and their bodies stop growing but their organs keep expanding. Goldfish are able to live over 10 years, if cared for properly.


Would seven guppies do okay in 2 gallon tank?

1 inch of fish per gallon so you about 18 but you will have the guppies eaten or the goldfish's fin bitten off as goldfish like to eat fish that are smaller than them (other than goldfish) and guppies are fin nippers so I would be careful or not keep them together good luck
