not sure about your tank size, but from what I've read, they are
supposed to be fine as long as you have a lot of plants for the females
to hide in, as the male will harrass them. You should get more than 2
females, as if you only have one, the male will harrass the lone female
until she gives up running and dies, 2 females will pick on each other,
more than 3 females is the desired set up I think, as they are bullies,
so you need to have at least 3 so you can establish a pecking order -
if only 2 females in the tank, one will be getting constantly bullied
by the more dominant one.

I have a 20G with 4 females (I used to have 5, one got sick and I
accidently killed her when I separated her from the others, I forgot to
dechlorinate her new water - DUHHH). I had my male in there as well,
which lasted about 5 hours, then one of my girls grabbed his tail and
spun him around a few times - since introducing him again a 2nd time,
she attempted this maneouver again! So I think it can be done, but
depends on the personality of the fish - I'm considering taking my male
basher of a female back to the store and swapping her for another one
to see if they can live in harmony or not. If that doesn't work, it's
tank divider time!
