A very good use for Fish Bowls is to use them as a vase. They should never be used to keep a fish in. They are far too small.
No. Charcoal bits will harm your betta fish. But you can use deactivated charcoal bits
Yes
Some people do not believe it but the best water to use in your betta fish tank is tap water. Bottled and distilled water has been "purified" and does not have the minerals that your Betta fish needs. If your tap water is so bad that you do not even drink it, than use spring water.
Betta fish live in rice paddies in places like Thailand. These paddies are miles long but shallow without much current. So the betta fish slowly developed the labyrinth organ which allows the fish to breathe air from the surface rather then use its gills.
Use a ruler and check every month
The Betta fish runs away when facing another Betta because its the first time facing another one. Or its just scared of it and doesn't want to fight since its not use to it and its a FIGHTING fish. But once its use to it the other Betta they well start getting up close to each other face to face and start ripping out each others fins out and basically trying to kill each other chasing each other around.
While you can use a jar for a betta fish, it is not an ideal environment. Jars typically lack adequate space, filtration, and heating, which are essential for the health of the fish. Betta fish need at least 5 gallons of water, along with proper water quality and temperature control, to thrive. It's best to provide a suitable aquarium setup for their well-being.
I would definitely not do this. The chemicals from the paint can be extremely toxic to the fish and can possibly be fatal. If you want your betta to stay healthy, do not use paint in their tank!
you posibily could but i wouldn't suggest it.
Beta fish just go to the bathroom like we do just in their thank or bowl.
A minimal tank size of 2.5 gallons is recommended for a single Betta fish.
Yes. First boil the shells in a pot on the stove. The heat gets rid of any bacteria or germs. You can aso put them in the rinse cycle in a dish washer, without any other dishes. (the soap is poisonous to your fish) Do not use any shells that curl or wrap over. Your betta's fins can get stuck. Use flat sheels. After washing them in the pot or dishwasher, allow them to dry over night. Then place them in your fish bowl.
