Plant ID please

This I'm guessing hitch hiked in with some other plants, its in my sump and growing quite nicely. Its a floating plant with no roots at all, it seems to have little air sacks like kelp does. Even guesses are welcome! This plant had me stumped!


The color differences are just from different kinds of light bulbs, there are 2 different clumps of this stuff so I took pics of each.

That's strange last week I notice something that looks the same amongst my java moss which I bought from another hobbiest about a month ago. Mine is still small at this time.

This is a few months growth. Its in my sump pulling out nutrients so I'm not to concerned about it, just getting curios on what it is because its growing so well and seems like it would be awesome in fry tanks!

could it be Water Sprite or Azolla?

But it does look alot like java moss ... i was doing research on plants lol

No none of those....

it is a type of plant-like algae.. i cant think of the name right now, it was discussed on APC awhile back.

Oh wow another structured algae? This will be my 2nd kind if it is!

mine looks the same but only like at a 1' ball now and no air sacs yet.

isnt that the same one you gave me Fern??

No it was just a little thing when I gave you plants so I didn't give you any

lol a little thing?? okkk

It seems to double in size every few days......

Mine is starting to grow quicker I put it in another 55 that has more lighting.

Its bladderwort!!!! http://plants.ifas.ufl.edu/node/462 Apparently there are a few forms..... at some point it will start having structure to it.
I took some to my lfs for an id

isn't bladdewort carnivoruos? I know some of the larger species are. An underwater venus flytrap plant.

Apparently, but its in the sump for my moorii tank so I think its fine....

The info on the link says so. I'd never heard of a carnivorous aquatic plant, but I like the sound of it. I may have to get some!! I know there is always plenty of food for such plants, just keep them out of your breeding tanks!

If mine get bladders it's going outside to control mosquitoes!

The bladders on mine are so small it would have issues getting a mosquito larvae....
