This is for betta fish but you can use it for other fish too but why would you keep a fish in a bowl tha's not a betta? Betta are the only fish that can stay in a bowl:
When you first get the fish clean out the bowl (make sure there's no dust or anything). How to clean the bowl the first time: At the first time you need completely new water for the fish. Wipe the bowl and make sure it doesn't have dust, residue, or anything dirty make it super clean and shiny. You'll need to put warmish water into the bowl and add water cleaner so it doesn't harm the fish. You can buy water cleaner from your local pet store (the one you got the fish from). And your bowl is ready to go.
Second time cleaning the bowl: Make sure you have a container to put your fish in when you clean the water. It has to be big enough so your fish can swim in it. Now you take just a little bit of the old water and keep it for the bowl after. Okay, now you take the fish out with a net and put it in a container with water in it. Now you take out the extra water in the bowl that has poop in it and stuff and put it down the sink or something. Then you clean the bowl if you have to and add water wih water cleaner into the bowl. Also leave some room for the old water from the bowl before it was cleaned so the betta doesn't get shocked or anything from the water change. Then, add water cleaner to the bowl again. Now take your fish out of the container with the net and put your fish back to where he was. That's about it. And also after a few weeks change ALL of the water and keep it warmish. If you change the water temperature to cold right away he'll go into shock for the change of temperature!
hope I helped :)
I clean my male betta's 1gal bowl at least once a week
4 days each like every 4 days you clean the bowl does not matter if its cold water fish or warm
Take the fish(s) out and put them ether in a bucket or big bowl then you are free to clean the fishtank. Make sure the bucket/bowl has a fair amount of water in it.
Once a week
When you are changing the water in a fish bowl, you have to empty cup ot bowl with water in it. Then, put it into clean water.
First get a bucket of water, and put the same volume as is in the bowl in the bucket. Let the bucket sit over night, and put water conditioner in it. Net the fish out of the bowl, and put it in the bucket with the new water. Rinse the bowl out, and sponge the inside to remove any algae. Clean, and put back the gravel and ornaments. Pour the water and fish back into the clean bowl. DONT USE SOAP.
feed it and clean the bowl
A fish will most likely die if you put a cleaning agent in its fish bowl without removing the fish. You should remove your fish with a net and place it in another safe container until fish bowl is clean.
once i week
Well usually every 3-4 days is best
no, only if your fish is appearing ill.
