I was wondering if it would be ok to house two female convicts in a tank i'm thinking of doing this because i've read that the coloring of females is a lot nicer and i'm really not set up to house any fry if i were to get a male and female. would there be any agression? and would two female convicts even do well in a tank that size, hopefully after they finish remodeling our house i'll have room for a 40g. well i appreciate all of your advice thanks.
