Can anyone help ID this plant and advise on trimming/propagating please?

1st pic think could be moneywort (bacopa monnieri)?
2nd yeh, hornwort, maybe soft hornwort
3rd .. hygrophila polysperma.. maybe!?

I think you might be right!

Have google image searched all of these, and some of the photos look spot on. It can be so hard to tell though can't it?! Even just google imaging "moneywort" gives so many different looking plants, plus the emmersed/submersed thing, where they look so different. I'm not 100% sure about the 3rd one being hygrophila polysperma, those seem to have a lot of varieties, so it's hard to tell, but I think it might be. I really need take some clearer close ups tomorrow.

Hornwort - oh my! I was confused about it because it looks like the stuff that grows in my garden pond, but it's a much softer texture, so I figured it must be a different plant. But I guess it's just a different species of hornwort! I found this quote on an article about hornwort: "The number of species is uncertain. Over 300 species names have been published, but there are likely only 100-150 species due to misidentification. "

I didn't know the moneywort could grow across the surface, that's awesome! I've been trimming and replanting cuttings when it got too tall, but think I'll let some reach the surface now and see how that looks. Thanks so much for the help with the idents! It's helped me figure out what I need to do now with some of these plants.

I think the hornwort could be green cabomba, just due to how it's 'leaves' appear to fan out.
I'm sure someone more knowledgeable on the subject can let us know

hair grass, doesn't do well underwater. Better off putting it in a pot with some potting mix and sitting that in a tray of water.

Ahhh, it could be! Honestly, there might even be a mix of cabomba and hornwort in there, I know a got several of these same type of bushy floating, stem plants, some fluffier than others, and some thrived while some of the more delicate looking ones shed needles like mad and didn't do so well, eventually dying off. Last time I moved things around, I bunched what remained together, so will have a closer look later, thank you! Oh, and some algae is growing on the older stems, making the ident even trickier. I've wanted to trim and tidy it up for a while, but the shrimp love it and there are always several of them hiding in it, including a load of tiny, see through baby shrimp they had recently. Made me nervous about putting scissors in there, or pulling any out.

Good to know, thanks! I've never tried the emmersed growing thing, so will do some research on growing hairgrass. Would be lovely to have several bunches of it growing in the different tanks, it looks really nice when it isn't tangled up or catching debris.
