Lots of cool things, but only a couple I’m interested in. These 3 pics are same plants. Opposite leaves. Rooting readily along stem.

Grasslike submerged, with possible fruiting structures.

I think the thin grass-like one may be Zannichellia palustris (horned pondweed).

https://www.illinoiswildflowers.info...rn_pondwd.html

The other I am thinking Hygrophila polysperma, since it's pretty much everywhere. Maybe this one will be different somehow, and I can call it "H. polysperma, 'Ohio'".

H. polysperma die off in the cold. It can't take hold in Ohio.

I took a quick fishing trip on a man made lake south of Columbus. The coolest think I saw was some sort of feret.

The mystery stem is certainly not Hygrophila. Instead, I think it's pretty likely to be a Veronica species. Either V. americana or V. anagallis-aquatica. Can't really say which.

Sounds like a mink.

No, it's on the small side with a light color underside. Oh, a weasel.

Well, that is certainly a new genus to me. I want to say I’ve heard of it before, and maybe even seen it out-n-about, but never in an aquarium setting.
Any knowledge of how it behaves in aquariums? If it grows as well as it did in the creek, I should be able to coax some emersed growth.
