I bought a bunch of this plant on my last trip to the LFS and planted it in the gravel. 3 Days later, it's almost reached the surface of my high tech! This is the fastest growing plant I have ever known, maybe even as rampant as Algae. However, I am finding it useful for low-light tanks, as not many stems thrive in low-light conditions.
This plant is very messy. As it grows taller, the lower leaves will fall off like pine needles off a christmas tree. It litters the substrate and clogs up my filter intakes. I do like that it is a fast growing plant, even without CO2. I use it mainly as a starter plant to combat algae during the initial phase of a new aquarium but I will be phasing it out soon.
You can just throw some hornwort in your aquarium and it will take over. The leaves tend to fall off. It grows even better with fertilizer and a good substrate. It is actually a floating plant, but it can be planted. It is very bouyant. It has tough needle-like leaves like a pine tree.
I just picked up a couple bunches for my 46g Tanganyikan African setup I have. The cichlids leave it alone, and it looks great. I've got a low light setup that needed a fast growing plant to outcompete the algae for nutrients. The crypts, apons, anubias, and taiwan moss were
just not cutting it.
This plant is indeed one of the fastest plants I have seen. Don't bother planting it, just leave it floating, either attached to a suction cup, or all over the top.
What I have also tried was to attach lead to the plant about 5cm spaces, and within a week it had created a curtain of green all the way to the top.
I now sell offshoots on ebay, at £1 for three 15cm stems.
If you get this plant soon it will take over your tank.
This is a fantastic plant!!!
It grows like there is no tomorrow! You should definantly use fertilizer for it though, or else it will die after a few months. I LOVE mine! It is perfect for a betta sorority tank, as it provides lots of cover.
I have this in a 20Long with a T8 18000k it seem to be doing ok however I think it may be too bright light for the plant I did plant it the sand. I may just move it all to my 55 and keep as a floating plant. However my mollies love to eat this.
This is a kewl plant, its pretty when it turns red on the tips (maybe how it flowers? its seen in the images on the right of the screen) I had this in my 55g with 108w T5ho growth lights for 10 hours, no co2 and little ferts (just some florapride 0-0-3) this thing took off, bi weekly trimmings, when i took it out finaly it was 6 foot long from end to end with many branch offs, I also put it into a extremely low light heavy stocked 10g my daught has and it grew to loosely cover the top of the tank, kept levels balanced didnt shed and didnt really grow either, I threw everything away but a 1" piece of a branch which i have in my new tank, i will see where it goes under 54w t5/good ferts/and 4-2 liter diy co2s
This plant is very common in northern lakes and ponds. I always keep it in my tank floating loose. It is easy to control by nipping off old browning part and the youngest fresh growing end will continue. It is good to cleanse water the natural way. It has one feature typical of aquatinc plants of northern latitudes. When light day becomes shorter in the fall, at a certain point, entire plant is shedding its leaves; it seems like it is dying. In fact, it is not. Do not worry, this is an adaptation to overwintering. I collect some still green tips and place them in a smaller tank for "overwintering". In spring, these buds will resume growing as usual until next fall, repeating the cycle. Possibly, I have the northern, not tropial stock known under the name Ceratophyllum demersum. This is why it sheds leaves in the fall, "like Christmas tree". If this is the case, I would rather have a real tropical origin Ceratophyllum submersum.
Fact is this plant does naturally grow rooted in the substrate, floats on the surface once disturbed. Young sprouts will often float. There's a lake in my canyon that is over grown with it. They grow little root like nodes if kept rooted long enough. I have never had the lower leaves fall off. Moved the plant from 50 degree F lake water into 76 degree F tank water with absolutely no problems.
I've had this plant for MONTHS but ive never really had much growth. I have moderate lighting, no CO2, ph around 6.8, temp 74F, and friendly community tetras and corys, and a betta. Other plants are great but this has never looked happy. I have some in other tanks but it never looks anything like the healthy plants in the pics -> WHYYYYYY!??!??!?!? :( i love the look of this plant and i want to keep it! HELP!!!
Not sure about keeping this in a tank you want to look pretty, but I keep hornwart in my garden koi ponds. The fish love it, great source of shade and fry hideout. Grows like wildfire but if it gets too bad just scoop some out!
I've never lost any plant yet in my aquarium except for this species not because it died. It was flushed in the toilet due to it being very messy. fastest growing plant I have ever owned but my substrate was littered with its leaves. Highly recommend it if you want to suck up excess nutrients. Also a great fry hideout.
Easily my fastest growing plant. In fact this might be a problem - it seems to be outcompeting my other plants for nutrients, making even the hygrophila grow slowly. Will probably need to up the fertilizer dose...
This plant grows in literally any light and freshwater condition. I have it growing in my high-ish lit 2.5 betta tank, and in a bottle sitting on a shelf with some ambient light hitting it. grows like 2 inches a day! craziness!
After all that good news, just something to watch out for! I always dip new plants from the lfs in a copper solution of 0.5ppm Cu, mainly to kill snails and their eggs. I've never known this (weak) solution to affect other plants, but this one lost ALL its needles after about 12 hrs.
I got this in a big batch of starter plants and it was great - no fertilizer, no Co2. But I did get the Northern variety. One day, in the Fall, all the needles fell off; what a mess. but i saved the stems and put them in a big vase on the dining table and they came back after a month or so. But beware, I did a Hydrogen Peroxide dip of all the plants in my tank because of cyano/diatom outbreak and all the plants came recovered except this one. Lost all it's leaves whatever's left is dwarfed and slow-growing... Update Oct/2014: Got another batch of this from AquaBid and it may be the southern variety - not terribly impressed with it. Could be a bad batch but it looks dirty and grows slowly.
I did not have good luck anchoring this plant in my tank. The plant looked nice toward the tips, bit closer to the bottom at the anchoring point would melt and make a mess. That, and it's an algae magnet... I would have to remove them from the tank, shake them off in some WC water just to get it all off! I eventually chucked them and went with jungle vals.
