I live in zone 3/4

, and we have a least two varieties of horsetail that grow natively in this area as well. It is super easy for me to grow as well, it grows all along my creek in my pasture, and it comes up every single year, I don't even have to plant it from seed. However when transplanting it to the aquarium, that changes. If you manage to keep it alive and healthy in your tank for over two years without a dormancy period, then you will have accomplished something that I can't find anyone else in the aquarium trade that has, including at least two people who make a portion of their living selling aquarium plants.
This tidbit taken from your linked article
"Plants prefer a half day of sun and high heat and humidity. If you live in USDA plant hardiness zones 7 – 10, horsetail is easy to grow. It’s best to start plants from seed
six weeks before the last frost and transplant outside in early spring."
Implies that your horsetail will require a dormancy period as well. It may be easy to grow "outside", but inside is a different story. Most of the plants that grow in the temperate zone require a dormancy period in order to remain healthy long term, otherwise they simply melt and fad away over time. I see lots of people who post up their experiences with equisetum or horsetail initially. As I said, I've even kept it for almost two years myself. I have yet to see a long term success story. Not that I would mind if you were the first, mind you, I would be thrilled if you pull it off. I just find it unlikely.
