Tailed Guppies Kissing

[bam_emma]

I have 2 yellow tailed guppies (1 female, 1 male) and in the night i got up and put my bedroom light on and they were both right at the top and front of the tank and were sort of kissing.
Is that how they have sex??

They also keep chasing my white molly, they arnt hurting it just keep following it, anyone know why?
I only got them yesterday.

The molly may be close to delivering some fry. Livebearers will follow each other around at a time like that hoping for a quick snack.

She's quite big mind, but they all were at the shop
