Guppy bulge

This guppy doesn’t even look that pregnant. Any thoughts on what is coming out of her here? Is it an egg sac?

Clamped male guppy with “growth” or “tumour” on underside.

Four guppy males in tank the rest seem ok. They’ve been in tank a week now and all’s been well until a few days ago when I noticed him occasionally clamping. He’s spent more time on his own than with other three from the very start which made him Mrs Lurch’s favourite. One of the others seemed...
