I have read that in a Saulosi community you should have one male but not two. Understanding the rationale that one male will kill the other. It follows that if you have multiple males have more than two. As long as you maintain a reasonable number of females to males is there a limit to males in the community? I presently have 5 males and 12 females (hoping to add a few more). These are housed in a 55 gallon tank. Should males be in odd numbers? Or if there are over three does it matter?
