From what I know about swordtails and mollies, the males can be decently aggressive towards each other without any females to distract them. Not sure if this would work, but I’m not an expert for these fish.Kevinthebreeder said:
I think three of each; one male for every two females. This ratio is good for livebearers because it creates a small harem for each male and lowers tensions. A 15 gallon is easily large enough to pull this off.Kevinthebreeder said:What do you think of a 15 gallon tank consisting of 2 green sailfin mollies and 2 wild swordtails ? Would it be okay if I also add 2 more non-sailfin mollies ?
Small tetras such as cardinals and glowlights are quite good. I prefer cardinals over neons as they are hardier and get that slight bit larger in size. Corydoras should be fine when kept with tetras.gms38 said:
Would an all male be okay ? Because the females don't look as good (Except for the non-sailfin mollies.).CrustyDusty said:
They may not be as attractive for the males but trust me it will be easier!Kevinthebreeder said:Would an all male be okay ? Because the females don't look as good (Except for the non-sailfin mollies.).
