Hello everyone,
I am considering getting several Swordtail's for the tank I am planning and love the little Lyretail's which is where my question comes from. I have been researching Swordtails and know that you should have 1 male to 3 or more females. But Lyretail males can't breed so my question is, can you keep a couple of the Lyretail males with another non-lyretail male Swordtail in the same tank? Not sure if the non-lyretail male somehow knows the other males are not competition and that there is no need to kill each other!!

Would have 3 females in the mix as well.
