Pond plant maintenance / clear - hornwort, duckweed and plant ID

[tr309]

Hi.

Second post on here. I'm on the path to taking care of and revitalising a newly inherited wildlife pond. The pond was a little neglected / overgrown when we moved in. I have 3 questions really:

1) There is a lot of what I think is hornwort which I know it's an oxygenator. Am I okay to remove a whole bunch of it as long as Ieave some in? It seems to be quite thick across maybe 50-60% of the pond.

2) I'm removing duckweed (toilet brush skimming seems to work well) and putting this in a container at the side. I'm trying my best to not remove any of the creatures i.e. kill them. Is there a good trick for this? When I say creatures... little bugs, dragonfly nymphs, snails and what look like leeches (?!)

3) Any ideas what plant this is? Is it good / bad / innocuous?

The pond is home to a few goldfish (we had a lot more until the frogs appeared in February and killed the goldfish - did not expect this), newts, currently tadpoles, and various other things.

Many thanks.

I pull hornwort a lot. Had a forest, of it.
Give it a good shake. Critters fall off. I keep a small amount growing, good egg laying area.

No idea on the plant.

I never had frogs kill off goldfish.

Thank you. I'll clear a bit more out.. seems quite vigorous.

I’ve never heard of frogs killing fish. Maybe sonething else got them. Birds & raccoons get them sometimes.
