Every week or every other week, depending on the size of the tank and the number of fish in it. The smaller the tank, and the more fish in it, the more often it will need cleaning.

How many goldfish for 30 gallon aquarium?

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.


About how long could two goldfish and a Chinese algae eater live in a 5 gallon tank?

Not Long. These different species of fish need totally different water temperatures and so should never be kept together. The Algea eater is a tropical fish and should never go below 70F. The goldfish are cold water fish and should be kept at around 55F to 65F. Applying the basic rule of all aquarists " 1 inch of fish needs a minimum of 1 gallon of water " you will see that the tank is far too small to accomodate even one goldfish properly so the life span of the goldfish depends on how often you change their water and how good the filter is.

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 offen do you clean a goldfish bowl?

Goldfish NEED 20 gallons for the first fish and an additional 10 gallons per additional goldfish. So for 3 goldfish you NEED a 40 gallon aquarium with A LOT of filtration. Your 3 goldfish will be dead soon due to both ammonia poisoning and lack of oxygen. Since goldfish have primitive gills, they require A LOT of dissolved oxygen in the water. Hence why they do better in unheated aquariums because cold water holds more dissolved oxygen then warm water does. You need to clean that bowl like 3 times a day. It is cruelty to keep them in there. Goldfish are America's number 1 mistreated and abused pet because people cram them in bowls. When properly cared for goldfish have lifespans of 30 yrs and grow 8-24 inches depending on variety. I have personally seen 14 inch black moors and have a picture of a 15 inch red oranda.
