It is possible to have two betta in an aquarium for a short while but you would need at least a 6 foot tank with heaps of water plants and other places like rock formations (hidey holes). The reason for this is to avoid them seeing one each other and a place for the victim to retreat to. Eventually they will meet and there will be fighting if you have two males, or flashing followed by nest building and spawning if you have a pair. Once the breeding is over the female will be fleeing.
Betta fish are best kept alone in a tank to ensure their well-being and optimal living conditions. Keeping multiple betta fish together can lead to aggression and stress, so it is recommended to have only one betta fish per tank.
No, betta fish are best as solitary fish, and unless they are going to mate, they do not swim together
No. They do not belong together. The toad will foul the water for the Betta.
A betta fish can last 2 - 5 years if kept in a tank with proper conditions.
No, snails and betta fish should not be kept together in the same tank as betta fish may attack and harm the snails.
Yes.
Only female Bettas can be kept together. That too will only work if they are given reasonably roomy conditions and plenty of cover (plants) and hidey holes. Male betta fish can/ will fight to death if there is another male fish in the tank, a male will sometimes eat a female so your best bet is to have a single betta or a female and a female.
Yes all bettas can mate with other bettas. " regular betta fish" there are different types and they can all breed together.
No, a snail cannot live peacefully with a betta fish as the betta fish may see the snail as food and attack it. It is not recommended to keep them together in the same tank.
No.
Gold fish require water below 70F and Bettas require water above 75F so they should not be kept together.
No they cannot, also if you put two Betta fish together, they will fight.
