Duckweed?

[marcus]

Does anyone know of any floating plants besides duckweed that is able to thrive despite condensation?

Also, do anyone have any experience growing mangrove? I recently got hold of a seedling and would like to know more about cultivation...
I´ve found some information on the web but it´s mostly about growing them in biofilters for saltwater aquariums.
I know this really doesn´t have much to do with floating plants but any answers would be appreciated

Depends what you mean by floating. Hornwort (Ceratophyllum demersum) floats, as does Indian fern (Ceratopteris sp.), though the latter prefers tropical temperatures.

Mangroves need brackish or full-strength seawater and very bright light (sunlight or metal halide).

Well... I was thinking more in terms about plants floating on the water surface, say like Pistia or for that matter ceratopteris.

Actually I am pretty sure that mangrove does fine in freshwater as I have seen it grown successfully in that manner but everyone seems to agree that bright light is important.
Hopefully the grey skies of Sweden will muster enough light to let the seedling thrive in my window, on sullen days fluorescent light have to lend a hand! If the mangrove seems unhappy I guess I have to make other arrangements...

Yup, Alan's right...we need to be careful and do some homework on our plants. I did seasonal work with Plant Protection and Quarantine in my college days, and the experiences opened my eyes. Many of the plants we like in aquariums are considered to be noxious, invasive introduced aquatic weeds in certain areas, and as such, they are subject to governmental monitoring, control and eradication. I sometimes think all of them have invaded the tropical waters of my home state. We all need to take care with the aquatics we use. They can be wonderful in your tank, and awful if you dump them carelessly into the environment.
