I just recently spilt my 2.5g and put the betta from my 1/2g into the otherside of the divider with the orignal betta that was already in the 2.5g on the other side and I was wondering how long would they be flaring at each other before they get used to each other and stop flaring? Also is there anything I should do to ensure that one of the bettas don't get on the same side and fight?
