This is a discussion on Amazon Sword Runners? within the Aquarium Plants forums, part of the Freshwater Fish and Aquariums category; -->
So I keep seeing One of the most common aquarium species of sword plants and one of the most hardy and beautiful. Mid-green leaves ...
So I keep seeing Amazon Sword with a whole string of runners and cannot get mine to send any off! It is currently in a ten gallon. Here are the specs-
Substrate- half and half mix between standard gravel and floramax gravel
Lighting-Marineland LEDs. Really, they are crap. There is only light in the middle of the tank and that isn't even much. Soon (once I get the glass hood), I am putting a 15 watt T8 light fixture on.
Ferts/CO2- I was dosing ferts and had DIY CO2 going, but it was too much in comparison with my crappy lighting and I kept having algae issues, so I stopped for now.
Are there any 'tricks' to get them to send out runners? My little narrow leaf chain swords are doing great and I have about 25 from the four I started with. I just can't figure it out. Hopefully you guys can point out something that I am missing or might help. Thanks!
The issue, more than likely, is the lighting. Typically, LED lights don't put off enough light for a planted tank. Once you get more light on the tank, some root tabs probably wouldn't hurt the plant either.
I have Pygmy chain sword which sends out runners like crazy (if the light isn't too low).
I also have Echinodorus amazonicus which is more of a regular sword (tube plant from petsmart). They can send up a flower stock (only one of mine has ever done it) but I don't know if they send out runners. A 10 gallon would be too small for these guys though.
I would assume light is your issue though. LEDs can be bright enough, but typical not the kind sold in most pet stores (I built my own that works). The Marineland Double Bright is one I think that does work for smaller tanks (just don't use the night light feature). A regular T8 tube is cheaper though.
Ok, the plant is an Amazon Sword, but I do have Pygmy chain sword in the same tank. I am going to make a trip to the LFS soon here to get my glass canopy (so that I can start using my T8 tube),some root tabs, and some of that liquid carbon CO2 stuff (I am done with my DIY setup). I have heard about DIY root tabs, but I think that can wait until a later time. As for the liquid CO2 carbon stuff. I know it is less effective, but my DIY setup is just too much for me to keep up with right now and I really don't need all that much CO2 anyways. Does all of this sound good? Thanks!
I have a couple of things that I have to wait and see to find out what's going on. I have a Melon Sword that now has two thin leaves going up, at the edge of the middle part where the leaves originate. I have to take a picture of them. As I see it, they could either be a new baby plant or some kind of hitchhiker plant (I've had this plant about a week and a half). I have had other leaves come up from the Melon Sword that looked to be typically shaped as the other leaves, but these are lanceolate? (long and thin). They look so different that I think it must be another type of plant and not a rootlet-based plant. Anyways, sorry to bother you with something I realize has absolutely nothing to do with Amazons sending out runners.
The other thing is some small crypts (probably, unidentified) which looked completely dead over two days - leaves completely lifeless - are starting I think to sprout again. I was hoping they would, but it still surprised me. May your Amazons multiply.
Most aquatic plant growers grow their swords more terrestrial. Swords can grow like this and actually grow faster, letting growers make more money. But when they are grown like this, their leaves are a different shape (roundish with a single stalk connecting it). When the sword is put in the fully aquatic setting, these leaves 'melt' and newer thin leaves come in. This sort of sounds like is happening in your scenario. I honestly didn't know what type of sword I had until these new leaves came in on mine. So just trim off the old "terrestrial" leaves and let the new aquatic leaves come in. About your crypts, it sounds like they just melted (shed all their leaves) and are sending out new leaves that are better suited for their new environment.
