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.

It's recommended to perform a partial water change of about 25% every 2-4 weeks in a 29-gallon fish tank. Additionally, you should clean the filter once a month and regularly remove any debris or waste from the tank to maintain water quality and a healthy environment for your fish.

A betta fish would be much more suited to a 1 gallon tank than a 'variety'. You shouldn't keep much more than one fish per gallon anyway.


How many gallon fish tank should you get for your 3 fish?

Depends on the kind and size of the fish. You should also take in to consideration how large they will get at adulthood. A good rule of thumb to go by is 1 gallon of water for every 1 inch of fish. So for example: 3 2" fish should be in at least 6 gallons of water. To be safe I would put them in a 10 gallon aquarium.


Can any kind of fish survive in a fish bowl with no filters?

Betta fish are about the only kind of fish that can survive with no filter. They prefer still water or a very gentle current, so as long as you are keeping their water warm and clean (at least 80* F) they will thrive in a one gallon, unfiltered bowl. Change the water at least weekly to keep a one-gallon betta tank clean. Change more often in anything smaller (and it's not recommended to keep them in anything smaller).


How often do you clean your half gallon fish tank?

I personally would empty it, then scrub it clean and use it occasionally as a flower vase. It is not large enough to keep any kind of fish in properly. The basic rules for keeping fish successfully are. :- 1 inch of fish needs at least 1 gallon of water (a Betta is a 3 inch fish). Every tank must have a permanently running 'cycled' filter. Every tank must have at least 50% of its water replaced every week. The above is not completely true. A Betta in a half gallon tank should have half of its water replaced each week. You should use a conditioner with that water (mine came with Nutrafin Betta Bowl Water Conditioner). I also make 20% of it HBH Betta H2O, which can be bought in bottles.


How often do you clean a fish bowl in a month?

Once a week


Can 4 guppies and 2 neon tetras go in a 2 gallon tank?

Yes, since Guppies and Neon Tetras are small fish (and stay small), there should be no problem with them living comfortably in a 2 gallon tank. You should add a little filter and air bubble combo to keep the water clean and aerated. Since these are tropical fish, you should also add a small heater and a thermometer. Goldfish do not need a heater but tropical fish do.
