Hi,
I have recently added two mollies (one black and one sailfin) to my tank and notice that the Sailfin is quite aggressive. I have not been able to find any information about this - everything I have read says they are pretty good community fish.
His aggression largely takes the form of chasing all other livebearers (guppies, platies and the black molly) - regardless of sex and species, for what seems to be the purpose of breeding.
The guppies(2) and other molly are male, and the 4 platies are females. I only have a 20 G - is this too small for him?
