I have 2 Blue Rams in a 20 gallon hex tank along with a mystery snail. 1 male and 1 female. should i add another female to the mix in hopes that the male will pair off with one or should i leave it alone and just go with what i have and hope that the male likes the female that is there? right now the male chases the female all over the tank but he doesn't seem to be trying to court her, it just looks like he is being mean.
