Help identifying plant

[sde]

Hey all,

So I have this plant that I get from a local marsh, and it does great in my tank! The thing is, I have no idea what it is. The closest I have found to it is wild parsley, but I don't think that's right. I will attach a picture of the plants in my tank and a picture of wild parsley. First three pictures is the plants in my tank ( pretty much they are the only one you can see ), and the second is of wild parsley.

What do you guys think it is?

I also find things that look like this, which grow into the plant i have.

But i don't think that they grow in marshes, so i really don't know.

Any thoughts? -Seth

Looks like celeriac :/ Does it smell of anything?

Looks a lot like "water celery" that we grow in ponds around here. (Oenanthe japonica)

It looks a bit like Hemlock Conium sp? I hope its not because that stuff is etremely toxic! Im probably wrong but you should definitely check.

No it doesn't smell like anything. The leaf pattern on the my plant looks a bit different too.

I don't think it is, the species you said has a very uniform and obvious pattern to it. There is the main stock and then there is a branch off on both sides going all the was up. That is not so on my ones, they grow wherever.

It does look quite a bit like water celery, doesn't it. Hmm, I will have to do a bit more research. Hard too say

Another thing to note is that a lot of them have a kind of bulb like thing, a lot like the ones that bellabelloo said.
Also they don't need to be rooted to grow and survive, I have some in my T. granulosa cooling setup that aren't rooted and are growing really nicely. I also have one in my T. granulosa's main tank that has the bulb thing and is just floating and is growing great as well.

Thanks for the suggestions guys! -Seth
