Swordtails

[Chri$]

I would like to keep a trio of male swordtails (not on there own obviously) in my new 20ukg when i eventuly get it setup. Would this work or would there be aggression problems?

from what we have been advised if you only have 3 males , let battle commence!

to have 3 males you would need at least 9 females (3 to one rule with livebearers)

Good idea - don't think i'd have the room tho unless i changed my stocking plans.

Well it will be best if you have 3 females for every male to lower aggresion. Unless you like your swordtails to fight constantly. Which I think is cruel. So to have the healthiest swortails possible have 3 females for every male. So is you want 5 males you will need 15 females to lower aggresion. That brings it to a grand total of 20 swordtails. Keep in mind that aggression can but stress on a fish. Stress on a fish will cause a increase in blood pressure, blood sugar, heart rate, and the release of cortisol. It can also cause the fish to breath very rapidly. Stress can have a negative affect on digestion, growth, reproduction, and chronic stress which will lower the ability of the immune system to respond effectively and fully. So keep a lot of things in mind when adding 5 male swordtails .

I had 3 male swordtails in a 55g with other fish once. Only one eventually made it.

This is a good idea in theory, for male Livebearers, but it's not suggested with aggressive fish such as Swords or Sailfin Mollies. With these fish, the more males, the more fish that will end up dead. These fish don't tolerate other males that well, especially if there are no females.
