Yes. Even though you see them in tiny containers in pet stores, they actually enjoy wide open spaces and lots of fun things to go under, hide behind and just explore. They will live much longer if you keep them in tanks and I therefore highly recommend putting your fish inside this big tank of yours. They, however, can live happily inside smaller bowls, or tanks, but they will only live for 1 or 2 years.
None are recommended if the Betta is a male.
No. Betta fish will attack each other no matter the sex.
keeping multiple bettas in the same tank is not reccomended
Male Betta splendens fight with other male Betta splendens so the answer is most other fish will not fight with a Betta in the same tank. To try to list every species of fish here would be impossible.
Any.
No, because they are fighting fish and one of them will kill the other.
Yes they will be happy because they can sleep in the plants and on the gravel.But the fish tank should be large for the fish so it has more room.I would get a large fish tank at petco they are a good price and work GREAT.
You should not put your Betta fish in the same tank in the first place, most likely the male will kill your other fish. by res do you mean red eared slider?
Female Betta fish can be fairly good community style fish and should be fine. Male Bettas would massacre the community.
Male and female betta fish should not be kept in a tank together unless the tank is large enough for a female to escape attack, there is a partition or they are breeding. Males will kill the females. They are very aggressive and are not schooling fish.
beta fish are very territorial if there is plenty of room for both of them in a tank they will just leave each other alone and another reason is that they haven't had to compete for food
A male beta fish blows a lot of bubbles. so if there are a ton of bubbles at the top of the bowl or tank, your fish is most likely a boy.
