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.
This depends on the fish that you have in the tank. Typically, all fish tanks that are not over-stocked should have weekly maintenance which includes a water change of at least 50%.
If you have your tank over-stocked, then you may need to do 2 water changes per week.
Make sure that you have a test kit and you monitor the ammonia, nitrites and nitrates which should be 0, 0 & less than 10 respectively.
If a fish tank is set up correctly in the first place, all it should need is a weekly (service) part water change (about 50%) during which the base/substrate is syphoned off and most of the rubbish is removed. The tank should not NEED cleaning out for several years.
You should look into the nitrogen cycle, until your tank is fully cycled, you should change half of the water every day for up to two months. If you do not inform yourself on the nitrogen cycle, how it works, and how to monitor it, your fish will most definitely die before the end of next month. Feel free to contact me and I will help get you on the right foot to keeping a healthy tank.
You should vaccum the gravel maybe once or twice a week because goldfish poop a lot.
you should do a 50% water change every other week
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.
Once a week :))))) i have experience
Goldfish can not get pregnant because Goldfish are egg layers. They spawn once a year usually during late spring. All adult fish need to be fed morning and evening. Growing youngsters should be fed more often.
If you arent going to do regular maintenance, keep it to 5 or less godlfish.
How often should you change the fuel filter?
Goldfish can lose their orange color due to light deficiency or dietary deficiencies. In these cases, the color change is often reversible.
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!
That depends on the number and size of the fish you have added in the tank. But as blanket recommendation you can do 50 percent water change once in a week.
every other week
No, but it should be cleaned with a syphon.
You should feed your fish as much as it can eat in 2-3 minutes twice a day.
