You don't! What you do is get a 55 gallon tank because angelfish won't be happy in a 10 gallon tank, and then you take the betta out of the tank (it will fight with your other fish) and just get more mollies and put lots of hiding places in the tank so the babies will live.
1 gallon tank what type of fish can you put in it?
