Ok....I have my 3 males in the 5 gallon, two sons and the father, and right now, one of the sons is uh....persuing his father. Like literally swimming up and doing what they would do to a female guppy. The poor father is darting away and doesn't want anything to do with it, but the son keeps persuing him.

I would seperate them, but the only other places are the goldie tank, betta tank, or the tank with the females, and I already have 58 fry, I'm not looking for more.

It is just a dominance thing, but it can become serious if he doesn't let his father rest. Since the tank is so small he has no place to hide and rest. Does he seem stressed or hide in the back or corners?

ok, ive just read your other post and i think your guppies are disturbed or something. get them to a doctor before they do something mad
lol

Yesterday I saw two of my male guppies kissing each other on the lips--no kidding! They would "kiss" then swim away a bit , then come back and kiss again--never saw them do that before.

There's plenty of plants for them to hide in, and two rocks set up with a cave under them. When they get too rough, I tap on the glass and they let up for a while. Throwing some worms in helps too.

Altho, right now, the dad is chasing them around. Guess he's tired of having unruly kids and is punishing them now.
