Well what do you think. I always thought they couldnt go with other fish either but I think there beautiful. My tank has two caves a hollowed out log and 4 medium size plants.
either sex would be fine. I just find them a very pretty fish. But I do not want the fish to attack or be attacked in my current tank. If there is a big chance then I wont take it.
Female bettas get along much easier than their male counterparts. But if you do get females, get at least 4 to prevent bullying. Female bettas are inexpensive, a bit hardy, and easy to care for.
