I am afraid that adding a #3 to this situation is not the answer.* It would only make the situation worse.* In THIS CASE AND THIS CASE ONLY the answer is to seperate the two females into 2 tanks and keep them seperated with NO other bettas with them.* Now that they have become this aggressive they may as well be males as far as their temperment goes.* They will not get along with any other bettas of either sex.* The reason that I can speak on this with such force is because I just went through the crumbling of my trio here.* My dominant female became very ill and had to be removed from a much larger tank than what you are speaking of.* The two who were left in the tank nearly killed each other trying to determine who was the boss.* I finally had one bloodied and bruised.* I had to start a 4th tank and I now have 4 bettas in 4 tanks, they are all aggressive as the dickens and none of them will ever make good tank mates to another of their own kind again.* (my dominant female did die so I did not have the option of reintroducing her to the tank and starting over or she would have whipped them into shape again, but the dominance needs to be established right away so with your friends fish this will not work]
This is why it is always a good idea to get 3 or more females AT ONE TIME and do not add more at a later time.* The original group will keep the newcomer from the food and starve them to death.* Bettas are different fish.* You cannot just put one in here and take one out there like you may be able to do with other species.* They just will not allow it.* Some days it is so hard not to stand in the middle of the floor and yell at the top of my lungs at them in total frustration, but I would not trade one of them for anything.* If you are going to keep Bettas, you have to be ready to do what the Betta needs, and it is usually the thing that is not what you want.* It costs money to keep fish.* The days of being able to buy a little bowl and stick a little fish in for the little kids are over.* We now know that this is cruel and inhumane.* Bettas are not pretty toys.* I am sorry to say that if your friend wants to have 2 betta females then he needs to take care of them or take one of them back to the store.* [and still get a good sized tank for the other]
You know all of this so why am I giving you the sermon* *
