What're they doing?

[DeeGeeDee]

Three of my male guppies have just started acting weird with each other. They constantly follow each other about and it's like they're kissing? There's no fin-nipping going on (or I just haven't seen it yet) so I'm reaching out for some help?

Is this a bad thing that I should be worried about? I can't seem to get the videos I have (iPhone) to upload!!

It's a dominance thing, called jaw-locking, many species of fish do it, nothing to worry about in itself, although keep any eye out in case any fishy arguments escalate!

Thank you, fluttermoth. It's the two biggest ones so that would make sense.
