Horsetail Rushes


Recommended Posts

Has anyone tried to grow horsetail indoors or in the aquarium?  I tried for years to grow it in planters and failed.  Then came the happy accident when I tied a rock to my last specimen and dropped it into the pond.  Now it is problematic.  I haven't thought this thru yet but I'm looking for something that the Tinfoil Barbs and other fish won't eat.

Generally needs more light than you can give it indoors 

Ohhhhhh...ok, that makes sense. Maybe if your tank set up included a pendant light of some kind, rather than just a tank light, it would do well. It'd be an interesting experiment. Let us know if you give it try.

So...if I'm understanding, it grew well in the pond?? If so, it should do fine in a tank. Why is it problematic? Does it spread quickly? Sounds like a planted-tank-keeper's dream plant, if so! 😉 


  I have a small 2 ft. tall waterfall, 3-6" deep stream, and the "pond" is one of those kidney shaped basins.  Over a two year period the Horsetail almost filled the stream bed and sent runners down into the pond.  Eventually it sends shoots back up and out of the pond.  It is a problem because it grows too well. removing it requires a sharp knife or saw and you sacrifice the substrate.  On the plus side, whatever variety I have only gets about 2' tall and the tiny blue flowers attract butterflies, and dragonflies.

I was curious as to whether it was harmful to fish as I've never seen it near a pond in the wild.

I would like to plant my 65 tall community tank. but so far the inhabitants have eaten everything.
