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.

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.


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.


What is the best kind of fish for a fish bowl?

No fish is best for a bowl, buy at-least a one gallon tank with filter, and you will clean it once every 2 to 4 weeks, a bowl will have to be cleaned every week. Also, your fish can swim better with more room, become less bored, and will be happier. If this is above your budget, fish is not for you.
