a gallon is much too much, a standard fish can fill a regular and average glass bowl, a gallon! Totally enough, I tell ya, you, the questioner.
If the goldfish is small enough for the eel to swallow, then you can confidently expect your goldfish to be eaten.
If the goldfish is a fancy variety, it can live alone in a 20 gallon tank. Goldfish do not belong in tanks any smaller than this as they grow very large
My advice is to get an actual fish tank and not just a bowl. Fish bowls are cruel and don't have near enough space for 2 goldfish to live in
One inch of goldfish per gallon of water is often recommended, so you could keep around 7-8 small goldfish in a 30 gallon aquarium. Keep in mind that as goldfish grow, they will require more space, so fewer fish may be ideal for the long term. It's always best to research the specific type of goldfish you have to ensure they have enough space to thrive.
No you schould not have that many fish in a one gallon tank. Thats the size of a big betta bowl. And because they are goldfish it is worse their poops are toxins
That is small better stick with a goldfish.
If the goldfish are small enough to be swallowed then in all probability that is what will happen.
For twenty small (1-1.5 inch) Goldfish you should have something like a 30 gallon aquarium.
Yes, goldfish are very messy. Goldfish need 10 gallons per fish, you actually need a 20 gallon tank or about a 70 liter tank for 2 goldfish. But the small tank will do while they are small, you will need to eventually get a larger tank.
The recommended tank size for keeping a goldfish in a healthy environment is at least 20 gallons for the first fish and an additional 10 gallons for each additional fish. A 3-gallon tank is not suitable for a goldfish as it is too small to provide enough space and proper filtration for the fish to thrive.
None! 1 goldfish can grow anywhere from 5 to 12 inches! It wouldn't live long because goldfish stunt their growth in small (unhealthy) spaces.
Goldfish need plenty of room to swim around and get very large. In a 1000 gallon pond you could put 25-50 goldfish just keep in mind that goldfish grow very large and need about 20-30 gallons each when full grown.
