I think it should be 10-20 gallons.
You can breed Bettas in a tank as small as 5 gallons, however, if you use a 20 gallon long, you can leave the fry in the same tank until they need to be jarred.
No, Betta fish are aggressive toward any other fish they see. They cannot mate.
The simple answer is no.
None are recommended if the Betta is a male.
None. The 1 gallon bowl is already too small for the betta by itself.
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.
you can put a betta in a 5 gallon tank
You don't! What you do is get a 55 gallon tank because angelfish won't be happy in a 10 gallon tank, and then you take the betta out of the tank (it will fight with your other fish) and just get more mollies and put lots of hiding places in the tank so the babies will live.
Go fish
yes of course! my betta is in a 2.5g and is perfectly fine
Typically, it is recommended to have only one betta fish in a 30-gallon tank to ensure they have enough space and territory to thrive.
A betta fish is the only fish that can stay in a bowl :) hope I helped :)
No. The tank is not large enough to house two female bettas. The basic fish keeping rule is "1 inch of fish needs 1 Gallon of water". A female Betta grows to around 1.5 inches so you would need at least a 3 gallon tank to house the 2 Bettas properly.
