Casey, I disagree with MRSKz totally. Bettas are infact hassled more by other, even smaller fish, than vice versa. I’ve found every single betta I have kept to be well natured, adds beautiful colour to a tank and will feed from your hand, I find them very friendly, not shy, absolutely wonderful fish.
They are not nocturnal; therefore putting them at night in a betta floating house is pointless.
