The cover is necessary for Bettas. It keeps the air above the water moist and warm so that when the Betta takes in a gulp of air it will not harm the fish.
you can put a betta in a 54 gallon tank
A large enough amount to cover half of the 10 gallon
A betta is best as a solitary fish and it would be better to remove it from your main tank and give it a small tank to itself. You can buy very inexpensive betta tank kits for one betta.
I've had trouble with this, too, you'll wanna have a cover over your Betta tank, or just discourage your cat from being around the tank (take the cat off the table, squirt it with a water bottle when it's there, etc.)
your betta will do just fine in close proximity to the turtle
Betta are airbreathers. So long as the ammonia and nitrates are okay, you don't need filters on a Betta tank.
put it in a tank with another male betta
I asked a person at petsmart and they said never put them in the same tanks bc they get terroitorial and they will fight! So i wouldn't try putting 2 betta fish in the same tank. But you can buy a tank that has a splitter in the middle with a blue cover that's plastic. They still will be in the same tank and won't know it!
betta bowl. it is amazing
Do not put any sharp angular things in the tank and do not put another type of fish in your betta's tank.
No, snails and betta fish should not be kept together in the same tank as betta fish may attack and harm the snails.
No your betta can live in a plastic tank as well. One of my betta fish live in an acrylic tank with silicon sealing the joint pieces.
