i want to get a betta cube, for a siamese fighting fish. i will only keep one fish, do i need a tank heater for it? my house is pretty warm most of the time, and i would leave the water to come to room temp before putting the fish in to it
i already have a 25 gallon tank, but the experts say that this is too big for a betta, and they like slow or non moving water and i have quite a powerful filter and air pump in mine. the tank i am looking at is specifically for betta's because apparently they dont need a lot of room and can be scared in a bigger tank. the other option i have is a 1.5 gallon tank, but still need a heater. i intend keeping the betta on his own.
