Is different size females in a sorority ok?
So I am cycling a ten gallon tank for a sorority and I have already purchased 3 different female bettas. One is a larger wild type and another is a pretty big veil tail- but I have a small crown tail as well. I am planning on picking up two more smaller females from petco as well. I know that I have to watch out for aggression and I have a ton of hiding spaces- but I am worried that the larger girls might beat up on the smaller girls. Has anyone noticed if by default larger females bully smaller ones? Also is it better to get females that are all one type of tail?
thanks in advance!
