Duckweed?

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.

    @Jokerjay, as in water dogs do you mean axolotls? i suggest very heavy research and a fully cycled tank before even considering purchasing one

    i highly recommend “buyanaxolotl.com”- ive purchased from them and received a beautiful animal for relatively cheap, in great condition, and excellent shipping precautions. the breeders are a couple living in georgia (i believe, don’t quite remember) and they’re fantastic. sometimes their website contact page doesn’t work, so i’d probably try just emailing them. good luck and happy hunting!

    Hi all I'm new here I'm just looking some advise on cycle witch is currently driving me insane . So we are week 8 I'm dosing daily with 4pp of amonia and for the last week has been dropping to zero witch I no is good. But my question is my nitrites are sitting at between 0.50 and 1.0 PM and nitrates are between 10 and 20 and neither of these seem to be dropping. I have done 2 40% water changes a few days ago and no change the only thing I can think of is I didnt use the seachem stability stuff which I have now ordered but surely that shouldn't have much difference this far into cycling

  • ytz13513:
    Dropping ammonia with rising nitrate and nitrite is good. It means the nitrifying bacteria is working. You just have to remove the nitrate from the water doing water changes. The level of nitrates is high and the nitrate is also high. The nitrite will be converted to nitrate using the beneficial bacteria and you can add them using quick start or allowing them to naturally grow in the tank. The latter option will take longer. The nitrate can be used by plants, so live plants can decrease the levels, but I would do a water change to get the nitrate at a level that is lower than 5 ppm. 5ppm of nitrate is natural and a good place.

    New here. hope this is the right place to post my question. I had 27 axolotyls aged 2-3 months old. main food has been finely chopped up bloodworms. no problems. I decided to introduce earthworms from my earthworm compost bin for variety. I finely chopped up 4 small earthworms and fed them to the babies. Within an hour 20 of the babies were dead. The remaining 7 (the smaller babies) survived and are now fine on bloodworms. Any ideas why the chopped up earthworms killed many of the babies?
