probably not. they have different kind of food and they might get mixed up
no they are two different species
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?
No. Betta fish will attack each other no matter the sex.
No, snails and betta fish should not be kept together in the same tank as betta fish may attack and harm the snails.
keeping multiple bettas in the same tank is not reccomended
Ghost Red Eared Slider Turtles will get to be the same size as normal Red Eared Slider Turtles, which is 10-12 inches.
No...betta fish are usually aggressive and might kill the angelfish.
Not necessarily. A Betta is a "Labyrinth fish" but all Labyrinth fish are not Bettas. All the Gouramis are Labyrinth fish too.
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.
Same way people do!
no
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.
