Can you gradually add females to a sorority tank, or do they all need to go in at the same time? I have had lots of boys, but never girls,and we have a spare very well planted ten gallon that I am thinking about turning into a sorority. Right now the only residents are 2 small cory cats and a mickey mouse platy.
1. Will the platy be ok, or should I move her?
2. How many females to a well planted 10 gallon?
3. I would prefer to start off with maybe 3 or 4 females and then add 1 or 2 down the line (as I see some I need/want/can't resist)... is this doable or do you need to start with all residents at the same time?
