If these fish are blue, they are males.
These aren't pair bonding fish, and can be quite hard on the females. I like to keep at least 6 females with a male.
The males can grow to 8".
Suffice to say, you've received really bad advice so far. I'll touch on the other points later, have to run for an appointment.
