Position in Aquascape:
Keep this plant trimmed down or it will take over quickly. Grows easily and would be a good plant for a beginner.
Grows fine if floated aswell. Easy to grow, tolerates low water temperature too.
Seems sensitive to Excel.
This is the first plant i put in my 10 gallon. 1.5watts per gallon, no co2, plain gravel, no ferts.... and it still grew about 2 inches in a week and sprouted a few new shoots... Definately could get out of control if you don't trim, but it's great if you want something that will fill in quickly.
I think it notable here that this plant can usually be found VERY cheap at most fish stores, as they sell it as fodder for goldfish and often have several bunches of it in their own gold fish tanks for the livestock to much on, which prevents them from having to spend money on fish food. If buying what they consider "real plants" at the same time, if you spot a "scrap" of it in the plant sales tank and ask, they will often toss it in with your purchase at no extra charge.
In case your interested, this plant will also survive in a pond over winter. Ive had it survive-28c temperatures, and come back stronger than ever in the spring.

Excel melts it without a doubt.
Another of my favourite stem plants. So easy to grow & take cuttings from. It's roots grow amazingly fast & that makes it very simple to make cuttings from. The fish don't seem to eat it at all & I have it in all my tanks.

This stuff grows fast! I had a couple cuttings about 5 inches long, and 3 weeks later I twice as many cuttings and they were a foot long. Excel will melt it, but API leaf zone is ok for it.
Excel will melt this plant, if excel is used sporadically. A continuous daily dosing of excel is fine. Just don't suddenly spike the plant with excel once a week or so. Either use it everyday, or hardly at all.
Amen to the using of Excel. I've used Excel every day since the day I put it into my tank and had no problem...other than it multiplying like crazy. I started with 8 stalks of it half way through April and I now have 43 stalks. Looks amazing in the background of my tank and is awesome for all my fish fry to hide out in.
I have a small lake inhabited by carp, and it is being infested with Elodea (Egeria) Densa. How can I kill this weed?
Goldfish seem to like chewing off the tops so that the plant no longer grows and must shoot out new branches from the side. Good looking and fast growing, but it succumbs quickly to goldfish attacks.
We are trying despirately to get this to grow in our Biology Department. For some reason it just won't grow... I love the way this plant looks and it makes for the best wet mount slides to examine cell walls due to it's 2cell thick leaves. Just wish it would grow reliably
This is the first plant I purchased for my brand new 10g. Unfortunately- I didn't know squat about planted tanks and I quickly made a mess of things. Totally melted the bottom portion of the plants. I think Anacharis is beautiful and I will give it another shot in my 'renovated' plant-ready tank.
I never seemed to have luck with this one no matter the water source. It would start out beautiful and full at the store and begin to look like a weed in my tank. It grows, but the leaves are no longer thick and full.
this can grow very long and thin when kept in low lighting. while in bright lighting it can be short. fast growing and about an inch a day is not bad. also known as elodea
I was given a stem of Anacharis when purchasing some shrimp from my LFS.. I'm amazed by how fast it's grown since I introduced it to my tank! Very easy to care for and grow.

I have very hard water and this plant stills grows about an inch a day. Excel melted all of the Egeria densa in 1 of my tanks so I stopped using it. Replanted the tank a couple of weeks later with cuttings from another tank is again growing about an inch a day. These plants look beautiful when grown in larger bunches.

Anyone know what the white strans are that grow off of these? I figured they were runners, so should I stick them in the sub. or can I cut them off. I have a bout 15 stems and at least half of them have these strans growing fron like half way up the stem
The perfect beginner plant. It will reach the top of your tank in no time and then you just pinch it off at the spot you want and replant in the substrate. It is common for one plant to have 5-6 shoots.
Man this is such not a beginner plant because mine dead after two weeks at least for me that is. The leaves melted away day by day and then it was a mess.
I love the look of these plants! Their cheap and grow like mad! Their great for anyone starting a new planted tank because they grow so quickly! I noticed any growth from the LFS will die off and new MUCH brighter shoots emerge from the old growth. You can just snip the new stem below the roots and discard any non rooted old original growth. I posted a picture just waiting for it to get validated! There is one MUCH darker stem in the middle of the picture. That is the only section of "Original growth" that survived for me. Every stem I propagated from the original growth has grown out well! I'd recommend it to anyone. Great stem plant!
Dont give up all together if you cannot keep this plant, Iv'e tried it 4 times and it always just dies, yet i can still keep plants like amazon sword and hair grass... weird!
Anacharis in general is a very hardy plant. It grows like weed even if given less than optimal conditions. However, there are a few things that can kill it: salt, excel, and high water temperature. All 3 of those can cause the infamous anacharis melt, where anacharis leaves turn transparent and mushy.
I have 1.7 W/US gal lighting (looking to increase) and even though elodea is supposedly a low light plant it isn't doing great in my tank, it doesn't root much so sometimes floats up, and some of the older leaves die, is this "melting" i dose Nutrafin PlantGro once a week, WHAT IS GOING ON!!!
i just got this plant like a week ago, and i have to say within two days it was already growing branches, and one is already about 2 1/2 inches long if not more and a few others coming along nicely. i have to say i'm very please with this plant. not a bad plant if you are starting to grow real plants in your aquarium.
Some interesting properties about this plant 1) its very good at absorbing nutrients very quickly good for messy fish but it can clear all the nutrients from slower plants 2) I can fight off cyanobacteria and algae because it secrets an anti-bacterial and other allopathic substances SEE http://kops.ub.uni-konstanz.de/bitstream/handle/urn:nbn:de:bsz:352-opus-49030/20.ErhardGross_2006_allelopathy_elodea_Aquat_Bot.pdf?sequence=1 3) this plant can lower PH in hard water inviornments because it actually uses bicarbonates to increase the electric potential within its 2 cell thick leaves. The top layer becomes alkaline and its lower leaves become more acidic as a result. THis plant can absorb calcites http://www.plantphysiol.org/content/91/1/62.full.pdf
Very Commonly known as Elodea Is Australia. Gold fish of plants. Kill this guy then your really doing something wrong. It Will grow just with the waste from your fish and the small co2 they produce. I let it grow to about a inch from the top of the water and cut it off and replant it sends of roots all the way up its stem can look alit omg at times gives off a jungle like feel when the roots bring it closer to the gravel.
Great beginner plant to quickly fill tank plant mass!!!

Anacharis would look really diluted green and unappealing in my tank until it started to grow shoots out the side. The shoots were really green and so healthy looking . As soon as the other anacharis started growing shoots I would just cut the shoots,plant them, and throw away the original plant. Now they're growing fine.

Unfortunately (or fortunately, depending upon how you look at it), this plant is found in most states in the US. So the good news is, if you come across it in the wild in any state, which is highly possible, you can collect it, but bringing it in or just simply having it in your possession in some states may have legal ramifications, so check the laws in your state; it would be bad to get "busted" for possession of this kind of "weed"! And as a general rule, don't let ANY of your aquarium inhabitants, either flora OR fauna, find their way into the natural environment. Even releasing native species back into the wild can introduce new pathogens into the environment that can devastate native species, so be responsible and don't do it. Also called "Brazillian Waterweed", Egeria densa is a "pest" plant that has been introduced into much of North America, with spotty distribution in the entirety of New England south of Maine, throughout the lower half of the U.S. and continuing up the west coast all the way to and including British Columbia, with particularly widespread areas in Florida, Louisiana, Oregon and Washington. It is legally categorized as a "noxious weed" in Alabama, Vermont and Washington, an "invasive aquatic plant" in Main and South Carolina, is under quarantine in Oregon and Washington, and it is "banned" and "prohibited" in Connecticut and Massachusetts, respectively. It adapts easily to most climates, so if you have this plant in your aquarium, take every precaution to keep it out of the natural environment and make sure to properly and sufficiently dispose of any you can't give away. If you don't have any in your aquarium, go out, find and collect some from the wild, 'cause Nature can use a hand in getting rid of it! Synonyms are Anacharis densa, Elodea densa, and Philotria densa.
