I have a 20 Gallon Tank and 3 betta females. Yes it's heated. Yes it's filtered. Yes it has been cycled. Yes there are many places to hide (plastic plants, tunnels, etc) They were introduced at the same time. It has only been 24 hours.
Unfortunately one of my girls, Isobel, was a bit of a brute and keeps chasing one of the other girls, Sparkle, and constantly flaring. Sparkle does not fare but does not back down, either. Isobel does not like it and keeps nipping at her. My third girl, It Zwibble, keeps to herself.
I have removed Isobel and placed her into the container we got from the store. It was stressing me out to see what was happening and I"m sure stressing the other's out more. Now I"m left with two and I'm debating on whether I should leave the two (which I"ve read is not a good thing) or trying another female (and hoping it's not aggressive). Or adding even more?
I'm fraid if I add even more like many sites suggest that the flaring will continue.
What do you think?
P.S. My 2.5 year old named the fish. " It Zwibble" is a name of a dinosaur fairy in an obscure 90's children's book (that we found in my old stash and now read to my kids)
