Read your other thread abit.
I would try and seperate the tank with a partitition if you can.
Rehome them.
Need to add the maracyn for there mouths first. http/www.aquariumguys.com/maracynplus.html
You can buy them from lfs, do you have some plastic that will slot in the tank to seperate the fighting fish.
This is just a solution till the fish can be rehomed fast.
