it could easily be done, if i was you i would buy a divider and a female and put the divider in and the female on one side for a week to let her settle in. and also see how the male reacts to this and the female aswell. if they are ok remove the divider after a week or so. if ure un sure then put a slot in the divider which the female can fit through but the male cant and see how things work.. if the male just wants to attack her straight away then that pair is not going to work.
if the male does not like this female strait away u could try another, how big is ure male? ure going to want a female that is nearly as big and if the male is matured then the female needs to be when u buy her aswell.
im sure some people on here are going to say that you will need a bigger tank 90G+ is ideal but i suspect it will be ok in there as long as u have decent filtration and keep up on maintenance.
Good Luck i hope this helps.
