About a week ago i added a new female betta to my 55 gal community aquarium which already included 1 female betta. I had always read that they got along well with other females and mine did until today. I got home from work today and did my normal feeding and watched them for a while and I noticed one chasing the other one from time to time. Really surprised me because from what I had observed this week they were getting along well together and at times would even swim together. The only thing i can figure out is that last night I added a piece of drift wood that is currently floating at the top of the tank. It seems that Dot has decided that this piece of wood is her territory and Lucy is not allowed near it. Are female bettas territorial? Is there anything I can do and have any of you had similar experiences?
