Here are a few suggestions. Please
keep in mind that many bettas are different and some may get along fine
with these fish where others will not. I have placed a next to my personal favorite tank mates. The African Dwarf Frog is
an excellent choice as they breathe from the surface just like bettas
and require no aeration.
*Some Bettas have been known to eat these,
others have not.
I have successfully kept many females and a male with them and I
also have lost all of my guppies due to female bettas, so it varies.
Just keep in mind that
bettas have long fins so keep away from any fin-nipping fish. I have
heard of people keeping them with Angelfish, but I have heard many
horror stories as well. When keeping female bettas in a tank together,
remember to give them plenty of hiding places and plant life to hide in.
Java Moss is a good choice for this.
