I didnt say four only twoWith female bettas you need 4+ to spread agression..and 4 wouldn't fit in your tank.![]()
if you had 2 female bettas one would get beaten to death so you need a minimum of 4 to spread out the aggresion and your tanks not big enough for 4
That's generally not enough space for a female community.I think you may be able to keep 4 in a 5.5 gallonn.
