How many females do you have? How were you able to get them to mingle with each other? I have never owned a female. I have always had males. But I do want to (later down the road) buy one. I would like to breed one day. I've been doing research on all of it and I think it would be a beautiful thing to experience. I already bread and raise my own guppies. However they are to feed my False Map Turtle.
I have 10 females in a 40 gallon tank :). They live together in sorority. Usually sororities are hit and miss but luckily mine worked out. All of my girls are relatively docile to one another in betta terms :p Females are fun to have. They also have big personalities like males.
Just some extra info on sororities:
The minimum tank size is 10 gallons
Minimum of 4 bettas, the more the better but keep in mind the size of the tank
Tends to work best when they go into the tank young or siblings
They should be all put in at the same time so one doesn't think they have intruders on their territory.
You have to be prepared if they don't work or if one gets beat up to much or one is to aggressive or if it falls apart- always have a back up plan
Unfortunetly sororities are not a %100 definite thing and sometimes all the sudden your girls cant stand each other and can no longer live together
Lots of cover and hiding places so the girls can get away from each other if need be
Some fin nipping is to be expected when first starting out as they are astablishing rank
Hopefully this was helpful :p
