cant tell too much from the picture, but maybe duckweed?

 

[Yahilles]

Picture is too small and we can't say for sure.

 

[Kaysie]

I thought duckweed too, but you really can't tell.

Kind of looks like Soleirolia soleirolii, but can´t be sure either....

Hi

Itlooks like Azolla Filiculoides, Water Fern, a native of North America, and can be quite invasive, it goes red in the autumn and tend to disappear a little in the coldest weather and come back with a vengeance in the spring

Hope this helps

I would guess a Salvinia species, but again, I'd need a closer shot to tell for sure.

Answers show that you have to upload better pic

 

[geganewt]

though this thread a tad older, it's azolla though and though

 

[Azhael]

I really think there´s no way that´s Azolla....
The picture is not clear enough but that plant defenitely has leaves as such, while azolla doesn´t...instead it has compacted filoids...

 

[KennyDB]

That is definately Azolla, I have a lot of it...

edit:
@Azhael: I think you see leaves in it because they're to much of them in that tank, on top of eachother and stuff?
Soleirolia isn't an aquatic plant, we use it as ground cover in gardens.

I'm beginning to doubt it to...but still Azolla really looks like that when it's so packed together...otherwise it can be some kind of Salvina?

A better picture would make it a lot easier.

Looks like a pile of Lemna minor to me (duckweed?) but I am not sure with this small picture.
