I believe its the females I have,
I also have some other tanks I tried with less females and more hiding places,
but I always end up with the same aggressive behavior towards the male, just takes a little longer for it to come out, but it does.,
Once I get it down to about 3 females things tend to change for the better towards the male, But even then only certain females work...
It's mostly aggressive tail grabbing that builds up until they riddle the male,
Mostly the bigger females,
I have actually watched them hunt the male down,
I have put plenty hiding places, plants etc, They still search until they find him and once they do they don't stop.
I am convinced males and females of any amount is a definite end in disaster, So I'm just not messing with it any more....
I have several lots where 1 or two females are with a male & it seems to work, But even then its certain females, Some just won't leave the male be no matter what...
Always in NEED & looking for more Tanks!
