Hey guys, So, I have a friend with a 20 gallon long tank with three male guppies (and a school of 10x harlequin rasboras and a 7 khuli loaches). She's interested in having some fry, but not heavily invested in helping them survive the other fish. However, she only wants to get one female and I'm not sure if this is wise. Would three male guppies harass a single female too much? Or would it be okay?
